Altough it is a bad practice to have such files :)

* Move code from function ClearProjectDrawList() into SCH_SCREEN object
  Clear() method.
* Delete eeschema/delsheet.cpp as none of the code in it is ever called.
* Move global spice and net list command line variables into SCH_EDIT_FRAME
  object as priviate members and provide access methods.
* Remove unnecessary header includes from eeschema/sheet.cpp.
* Minor coding policy fixes.

- first, matches are now filtered with component filters (as set in eeschema lib editor);
- second, if two or more matches exist, first one will be accepted in accordance to
  alias file order set in project prefs, and then to order of lines in file.

For example you may have such configuration

.equ:
'100' 'CAP100'
'100' 'RES300' 

C component have filter 'CAP*'
R component have filter 'RES*'

So R with value 100 (IEEE/ESKD short for 100 Ohm) will get 'RES300' footprint,
and C with value 100 (IEEE/ESKD short for 100 pF) will get 'CAP100'.

Also equ read routine is rewritten so it is now gracefully accept UTF-8 and spaces.

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)
