Scripting: fix compatibility current pcbnew version in 2 examples and the default extension of board files in board.i (was .kicad_brd, now is .kicad_pcb)
Remove KICAD_GOST option because it is now useless: the 2 GOST options are now selectable at run time and are:
* specific page layouts (now user definable, and the GOST page layouts are available in template folder)
* notation for multiple parts per package (made in eeschema, preference menu)
File "rules" has instructional text as comments near top.
2) Convert all text files in repo to LF line ending form.
Any checkout done with "rules" in play will convert the working
tree to native line ending, while keeping repo as LF line ending.
* Improve the stable and testing build version option logic.
* Use CMake FindPythonInterp to configure the Python interpreter.
* Use Python interpreter to determine the system Python module install
path if not already defined on the command line.
* Add header symbol checks for asinh(), acosh(), and atanh().
* Add test source to check for isinf() which can be defined as a C++template.
* Replace conditional compile on windows systems for aXXXh() with CMake
configuration tests.
* A few minor MSVC compile fixes.
* Fix incorrect python environment string in fixswigimports.py
* Create a separate document for KiCad CMake build options.
* Create a separate how to compile KiCad on Windows document.
* Derive the pcbnew copper zone and non-copper zone dialog windows from DIAG_SHIM,
which injects some template code.
* Update UIpolicies.txt to talk about DIALOG_SHIM support.
* Add zone support to eagle_plugin.
* Organize ZONE_CONTAINER class declaration for future privacy and accessors.
* Correct all user strings and comments for the correct capitalization of
application names according to JP. They are KiCad, Pcbnew, CvPcb,
Eeschema, and GerbView.
* Add a note the the user interface policy about the correct capitalization.
* Add USE_IMAGES_IN_MENUS definition to override the default platform
behavior for adding images to menu items.
* Update COMPILING.txt to document how to use USE_IMAGES_IN_MENUS.
* Fix Windows segfault when creating language selection submenu introduced
by new bitmap code in r3087.
* Changed per email from JP from CVPcb to CvPcb because I'm getting old and
blind and misread the email.
* Lot's of Doxygen comment and coding style policy fixes.
