Pcbnew: fix a minor issue.
Version update.

Annotation of multiparts gets CHINAME compared. This fixes bug when annotating components of same value (model) in several forms (e.g. dual opamp in single-body and dedicated representation).

* Fix debug build warning (lp:793373).
* Changed sheet edit restore and undo to use object copy and replace method.
* Add minimum width and height constraints when resizing sheets that have
  hierarchical pins.
* Fix drag sheet hot key bug.
* Change Doxygen configuration to extract private methods and members
  when creating documentation.
* Fix a bunch of Doxygen comment warnings.

dialog_about: add translator name.

Try to fix bug 639683 : Illegal reference strings are now detected and replaced by default prefix for old schematics or rejected in schematic edition.

Eeschema: add direct acces to LibEdit in popup menu, when a component is selected ( Whishlist #788621 ). This new command calls Libedit and load the lib component corresponding to the selected schematic component.

Libedit: actual line thickness  taken in account by collector. Thick lines are now more easy to locate. Fix incorrect boundary box calculations for LIB_PIN items. Very minor other fixes.

* Add drag context menu entry for junctions that actually form a junction
  with wires to EESchema.
* Add function to test for junctions to SCH_COLLECTOR class.
* Create annotate type and sort order enums to eliminate magic numbers
  used in annotate code.
* Remove duplicate Doxygen comments from annotate.cpp and improve the
  actual Doxygen comments in wxEeschemaStruct.h.

Pcbnew: fix very minor issue.

* Remove most (not all) variables that were initialized but never used that
  cause GCC 4.6 to generate a warning.
* Fix bug in schematic library editor best zoom calculation.

Minor other fixes.

Pcbnew: bug fix: in rare cases, solid copper areas are to large (minimum width not taken in account to calculate filled areas)

Pcbnew: refresh issue with dialog designe rules under wxWidgets 2.9.2 under WINDOWS (replace wxChoiceBox by wxComboBox, should not change anything for users)
Eeschema: some  issues in libedit (when editing a pin )

Eeschema: bug fix: after a "De Morgan" convert command, the component was left selected (.m_Flags not cleared)

* Create library collector class.
* Add clarification menu to library editor when multiple items are found
  at the current position.
* Add get clarification menu text to all objects derived from LIB_ITEM.
* Add get menu bitmap for all objects derived from LIB_ITEM.
* Improve LIB_PIN bounding box calculation.
* Rename LIB_ITEM::DoGenCopy to doClone to match behavior defined in base
  class EDA_ITEM.
* Minor class renaming for improved code consistency.
* Added less than operator to EDA_ITEM.
