fix an issue created by commit 2954. Gerbview: display now an indicator of layers in use. minor code cleanup.

* Move undo item copy global variable into schematic editor frame object
  member variable.
* Add helper methods for accessing the undo item copy member variable.
* Fix undetected bug when changing a text type.
* Added an exchange command to the undo/redo base class for handling undoing
  a changed item type which cannot be undone by swapping out the variables.
* Revert change to common/hotkeys_basic.cpp that broke hot key behavior.
* Lots of coding policy changes while making the changes above.

* store selected language by name instead of wx language id (that changes between wxWidgets version)
* accept always comma and point as flotating point separator.

* Fixed minor code formatting issues with submitted patch.
* Change field name to "spice_model" per discussion with Charles McDowell.

* Change all code references to pin sheet and sheet label to sheet pin to
  more closely match the sheet pin object for improved code readability.
* Change menu and tool bar text from pin sheet to sheet pin for improved
  user readability.
* Moved sheet pin place method to sheet pin object source file.
* Move last sheet pin stored state information into schematic frame object.
* Add Doxygen comments for the sheet pin editing methods.

* Rename EDA_Rect class to EDA_RECT.
* Rename EDA_TextStruct class to EDA_TEXT.
* Remove duplicate Doxygen comments from sch_sheet_path.cpp.

* Remove specialized edit reference, value, and foot print field methods
  from SCH_FRAME object.
* Improve general field method to handle all field types as this was
  essentially the same code used in the three methods removed.
* Updated the the hot key and context menu handlers to use the new field
  edit method.
* Minor Doxygen comment warning fixes.

fix 2 minor bugs: GERBVIEW: Button "Erase all layers" not working, EESCHEMA: Plot to Clipboard: EDA_DRAW_FRAME::PrintPage() error

* Push schematic back annotation code down into the appropriate class.
* Minor improvements to back annotate file selection code and user prompt
  strings.
* Minor tool bar tool tip capitalization fixes.
* Change tool bar ID error from message dialog to a debug assert message.

* Set default button on all dialogs that do not already have a defined
  default button.  The only exception is the EESchema net list dialog
  which needs converted over to wxFormBuilder and due to it's design makes
  setting the default button in any tab other than the default tab
  problematic.
* Fix escape key dialog handling bug in EESchema print post script
  dialog.

others: fix minor issues.

* Remove clearance and net class name read only text boxes from PCBNew
  auxiliary tool bar.
* Display full net class information in message panel when an object that
  supports net classes is selected.
* Move coordinate string conversion function to EDA_DRAW_FRAME object and
  made it more versatile.
* Refresh message panel text when units change.

* Move locate function code into schematic screen object.
* Move test for junction needed into schematic screen object.
* Move test for marking connected items into schematic screen object.
* Move delete item function code into schematic screen object.
* Move delete all markers code into schematic screen object.
* Add method for locating multiple items in schematic screen object.
* Fix minor bug in schematic field object hit test declaration.
* Initial encapsulation work on item picker object.
* Remove duplicate doxygen comments from item picker object source file.

All: fix a minor bur annoying issue: incorrect cursor shape after a block command (mainly when a tool is selected)

* Factor change schematic component orientation code out of switch statement
  into separate function.
* Remove redundant command events from schematic editor hot key handler.

* Change EDA_ITEM set flag function to set flag bits using logical or
  instead of assignment.
* Add clear flag function to EDA_ITEM to clear flag bit using inverted
  logical and.
* Factor change schematic text type code out of switch statement into
  a single function call.
* Schematic text orientation function renaming improvements.
* Lots of small coding policy changes to updated files.

All : modify macro FROM_UTF8, to ensure compatibility with files using a non utf8 encoding (old files created under Window, having some non ASCII characters).

* Factor component unit select handling out of huge switch statement into
  a separate function.

* Fix grid select box update bug on context menu.
* Fix via size and track width select box update bugs.
* Fix layer pair indicator button update bug.
* Fix auto track width tool bar control enable bug.
* Fix via size and track width select status bug in context menu.
* Fix layer select box and layer control widget select bug when current
  layer is removed.
* Add virtual function to notify objects derived from EDA_DRAW_FRAME that
  the units setting has changed.
* Coding policy class naming fixes.

Use UTF-8 encoding only in kicad files. Under Linux, this was already the case. Under Windows, texts with  non ascii characters must be corrected.
This ensure compatibility between platforms.
