Fix minor aesthetic issues in dialogs (these minor issues (overlapping widgets)  exit only with some Windows managers like KDE)

Very minor fixes: add missing const return type to some GetBoundingBox() declarations. Change few functions names to better names in some places (like GetName() to GetPinName() )

Minor and very minors fixes: move -DKICAD_USE_WEBKIT definition to the main CMakeLists.txt. Remove duplicate semi-colon at end of some lines.

Road map: Gerber X2 file function extension marked done in Pcbnew and Gerbview

BOM dialog: remove a not very useful button, and merge its function with an other (not perfect, need more work)
Add message box to show info added in BOM python scripts (See scripts/bom-in-python/README-bom.txt about this info)

Eeschema: Netlist generator: remove option to generate the fully outdated old netlist file format (based on a very old Orcad netlist format)
Only the new (S expression) better netlist file format is now used.

Try to fix issues on Ubuntu/Unity for dialogs which are not displayed: adding GetSizer()->Fit( this ) in some other dialogs

Try to fix an issue on Ubuntu/Unity for some dialogs which are not displayed. For most, adding GetSizer()->Fit( this ) in dialog constructor fix the issue, but at least one dialog still is not displayed.

* Fix assertions in Eeschema when editing net labels, electronic rules check,
  and plotting.
* Fix assertion when opening PCB calculator.
* Fix assertions in Pcbnew when changing footprints in footprint properties
  dialog and adding or editing text.

Fix many doxygen warnings (due to missing info, old comments, typo ...) when building the doxygen doc.

Eeschema, Plot dialog: add Plot directory selection. The patch from 1383026@bugs.launchpad.net was widely used.

eeschema: fix Bug #1385789 (eeschema segfaults, when editing a new field). Fix an other minor bug in Footprint editor.

Add FILE_NAME_WITH_PATH_CHAR_VALIDATOR, a custom wxValidator which allows file names with paths, in schematic sheet editor
( FILE_NAME_CHAR_VALIDATOR previously used in this dialog does not allow chars used in path names, like / and on Windows \ and : )

Fix dialog title to be "Electrical Rules Checker" to match everywhere else.
Fix all usages of "Erc" to "ERC" consistently.
Move action buttons to bottom of dialog, make Del Markers actually say Delete Markers.
Add tooltips to ERC options matrix buttons to indicate what their current state is, for newb friendliness.
Cleanup ERC options code that for some reason decided to delete the button and recreate it instead of just updating it's bitmap directly.
Rename "Test Erc" to "Run" because you are running ERC and not testing it.
Fix improper usage of SetLabel on a wxTextCtrl instead of SetValue so the ERC totals now work!
