Libedit: fixed draw artefacts when editing a graphic symbol. fixed minor issues in undo and abort commands when editing graphic items.

Make option not uppercasing component names. I'm so bored with my Eeschema is convert ADuC, Si, component names to ADUC, SI etc., so I contribute this patch so anyone now may keep components

* Fix bug that prevented component from being replaced in library when
  the component root name was changed.
* Fix drawing bug when changing text or field item string while move in
  progress.
* Fix drawing bug when rotating text item while move in progress.
* Prevent undo or redo when editing a component draw item.
* Fix assert bug when replacing component in library when the component
  root name was changed.
* Fix bug in field editor caused by new root alias implementation that
  prevented any field from being changed.
* Fix minor spacing issues with EESchema find dialog.
* Deprecate remaining internal linked list code from component library
  objects.
* Rename pin object files to match new library object file naming
  scheme.
* Move LIB_TEXT object definition into it's own header file.

STRING_LINE_READER::ReadLine() has been broken for a few weeks, since changing the purpose of member 'source'

* All library component object editing is now performed with the ojbect
  except LIB_PIN (coming soon).
* Added TRANFORM class to handle coordinate transforms.
* Remove old transform matrix functions.
* More file renaming to align them with the other component library
  object file names.
* Fix hot key bugs in library editor to disable edit keys while an item
  is being edited.
* Fixed bug when cancelling rotation of text and field objects while
  being moved.

Eeschema: added pin names in search function. Fixed minor issues in search function. Known bug: "search next"  searches for pins in next component, not the next pin in the same component.
Pcbnew: fixed an old minor issue when moving the layer manager window (not fully fixed, but  wxAuiManager seems have minor bugs and lacks).

Gerbview: Fixed compil problem in debug Mode. Pcbnew: try to fix an issue in export gencad  (incorrect rectangular pads)

Gerbview: Added support for gerber command   SR (Step and Repeat) and multiple MOIN and MOMM in file

      
      It follows the CMake wiki 
      
      http://www.cmake.org/Wiki/CMake_FAQ#Can_I_do_.22make_uninstall.22_with_CMake.3F
      
      and it should work if one
      compiles from the build directory (building all kicad).
      
      You can use it running the following commands from the kicad source
      tree root:
      mkdir build
      cd build
      cmake ../
      make
      (using root) make install
      (using root) make uninstall

Gerbview: added support forSF (scale factor), IO (Image Offset), OF (Offset) and MI (Mirror) commands.

Gerbview: added  support forSF  (scale factor), IO (Image Offset), OF (Offset) and MI (Mirror) commands.

Fixed a bug about Aperture Definition having parameters for an aperture macro. See Changlog for not yet supported RX274X commands. Having still problems with arcs in some gereber files.

* Break classes_body_item.cpp(.h) into more reasonable size bites.
* Rename classes_body_item.cpp(.h) to lib_draw_item.cpp(.h)
* Fix some unsatisfied header file dependencies.
* Add stubs to component library draw item base classe to handle editing
  internally.
* Lots of code cleaning.
