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!

BOARD::Add(): fix an issue for tracks: parent not set (could be an issue only in python scripts, because the parent is set by the constructor)
*.i : fix coding style issues.
python method: add BOARD_ITEM Duplicate, which is a wrapper to Clone(). ( defined as Cast_to_BOARD_ITEM(selt.Clone()).Cast() )
update some .py examples.

Pcbnew: fix some issues when using python scripting (remove outdated SEG_ZONE item, fix broken access to netclass, track width and via size lists, add missing access to zones)
Update listPcb.py to show how to access zones.

Update clipper version to 6.1.3a.

Also update main toolbar track width and via size info in pns router mode, when starting a track, and other very minor update issue.

change name TEXTE_MODULE::MirrorWithModule to TEXTE_MODULE::MirrorTransformWithModule, because it is a function specific  to a footprint transform in modedit.
change also name TEXTE_MODULE::RotateWithModule to TEXTE_MODULE::RotateTransformWithModule for same reason.
Pcbnew: fix Bug #1374484 (text changes position when module is flipped and rotated). Fix also some bugs in modedit, in block commands.

* Remove ${CMAKE_CURRENT_LIST_DIR} copied FindPackageHandleStandardArgs.cmake.
* Comment out debug messages in FindwxWidgets.cmake.

* Add version detection to FindwxWidgets.cmake
* Convert commands and macro names to lower case in FindwxWidgets.cmake.
* Use find_package_handle_standard_args() to handle version comparison.
* Update FindPackageHandleStandardArgs.cmake from CMake 3.0.2 to get the

  use find_package() the way it is supposed to work unless the developer
  specifically requests building everything from source.

fix recent bug which prevent eeschema to save color preferences.
fix few other minor issues.
