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)
* Add hotkey fast switch to two grids: for place and trace
Alt+"1" - switch grid for place module
Alt+"2" - switch grid for trace
This two grid set in dialog - menu Preferences->Dimensions->Grid.
* Add hotkey switch grid:
"`" - switch to next grid
Ctrl+"`" - switch to previous grid
* Add hotkey switch track width:
"W" - switch to next track width
Ctrl+"W" - switch to previous track width
cmakemodules:
* Add GOST to KICAD_BUILD_VERSION if define KICAD_GOST.
