Very minor enhancement in module edition dialogs.
Fix a minor bug in design rules editor: in Global Rules Edition: drill values > via diameter not checked
and the first item (track or via) in list was not checked (explains Bug 702177, that is not really a bug)

Pcbnew: fix that prevents loading modules from libraries (footprint name not identified in lib)
Module Editor: Try to fix incorrect printing. Fixed now only for scale 1. Nor working for other scales. (Work in progress).
Gerbview: Known bug: printing not working.
VRML export: Fix incorrect export of 3D shapes rotations when the 3D shape was rotated.

* Make global variable g_ItemToRepeat a private member of SCH_EDIT_FRAME
  object.
* Encapsulate SCH_SCREEN reference count member.

* Change default build to enable wxDC zooming.
* Move sheet label find function into SCH_SCREEN object.
* Move draw screen items function into SCH_SCREEN object.
* Remove redundant page print method from SCH_EDIT_FRAME.

Eeschema: fix incorrect undo behavior after a component edition using the dialog frame (some changes were not undoable).
Fix incorrect behavior after unit selection using the popup menu,  and add undo command after this change (was non undoable)

* Merge LocateAnyPin() and LocatePinEnd() into single method and move to
  SCH_SCREEN object.

Eeschema: minor enhancement: When a netlist is created and a component is not yet annotated, the annotate dialog is called from the netlist dialog
(no need to close the netlist dialog, open  the annotated dialog and reopen the netlist dialog).

* Move update block pick list code to SCH_SCREEN object.
* Remove redundant drawing function RedrawOneStruct().
* Change context menu text "Noconn" to "No Connect".
* Change context menu text "GLabel" to "Global Label".

Add edit menu and right-click menu items to pcbnew for resetting module and other text field sizes to current defaults set in Preferences->Dimensions->Texts and Drawings.

* Add test to schematic objects for connectability.
* Make copy block items function a private method in SCH_EDIT_FRAME.

* Schematic reference object now completely encapsulated.
* Schematic reference list object refactoring complete.
* Make OK default button in PCBNew block operation dialog.

* More schematic reference list object refactoring.
* Initial encapsultation of schematic reference object.
* Improve schematic reference object doxygen comments.
* Remove redundant library component lookup when generating net list.
* Fix doxygen waring in LIB_PIN object.

Pcbnew: Bug fix: arcs in modules outlines (when flipped) were incorrectly saved and read  in .brd files.
this was due to incorrect macro NORMALIZE_ANGLE (was the same as NORMALIZE_ANGLE_POS), now modified and renamed NORMALIZE_ANGLE_360

Fix a minor warning when starting Kicad in debug mode (wxWidgets 2.9.1 specific)

  * Added the basic structure to the Sweet parser in sch_part.cpp.
  * Got inheritence working off of the 'extends' keyword and PART::inherit()
  * Tossed the units support out of sweet.keywords, since we agreed to go dimensionless.
++richio:
  * Added the problemInputLine support to PARSE_ERROR, so UI can show the
    offending line of bytes.  Yes bytes, not even guaranteed to be characters.
