* Move schematic wire and bus break code into schematic screen object.
* Move schematic test for dangling ends into schematic screen object.
* Remove left over debugging output in schematic screen object.
* Remove unused file eeschema/cleanup.cpp.
* Fix bug in schematic line object hit test algorithm.
* Fix a string concatenation compile error added in r2752.
* Rename class WinEDA_BasicFrame to EDA_BASE_FRAME.
* Rename class WinEDA_DrawFrame to EDA_DRAW_FRAME.
* Rename class WinEDA_DrawPanel to EDA_DRAW_PANEL.
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)
* Moved ReturnLayerName() to static BOARD::GetDefaultLayerName() and migrated
to a Specctra DSN compatible default layer naming scheme:
Component becomes Front, Copper becomes Back.
* set_color.h: Cmp becomes Front, Cu becomes Back.
* D_PAD::DisplayInfo() changed to use actual copper layer names.
* more layer setup dialog work, moved all programmatic wxControl instantiation
into the wxFormbuilder environment, but this is fraught with danger:
wxFlexGridSizer used the tallest control to establish the row heights, so
be careful about changing control borders in the scroll panel. The vertical
size can explode since just a couple of pixels times the number of rows
is substantial. Currently I am setting a 5 pixel border only left, top, and right
but not bottom.
* Set copper layer count is back in place as a hack until I can get the enabled
layer bit map fully operational.
* Replace all known instances of (const wxChar*) casts to GetChars() for
wxWidgets 2.9 compatibility.
* Cleaned up get component dialog so last part gets saved on wild card
selections.
* Remove redundant schematic component drawing code.
* Added SCH_COMPONENT constructor to create new component from library
component object.
* Add message panel helpers to WinEDA_DrawFrame and update old message
panel access code.
* Using library viewer to add component to schematic now respects unit
and body style selection.
* Split out application specific command IDs to prevent unnecessary rebuilding.
* Eliminate duplicate menu and tool bar command IDs.
* Split component library editor and viewer definitions to separate header files.
* More component library and document file merge code.
* A bunch of minor string readability and consistency fixes.
