TundraVersionInfo.h: make TUNDRA_VERSION_STRING an arbitrary string instead of automatically concatenated string so that f.ex. we don't get unnecessary trailing zeros and we can append possible version postfix.
Application: fix bug that caused version string with postfixes to be parsed wrong. Use the defines in TundraVersionInfo.h for the Application version information.
VersionCheck.js typo fix.
root CMakeLists.txt: suppress CMake policy warning. Fix typos in version definition names.
Add version information to Tundra Windows executables.
