Add build type to -version

This adds the build type in brackets in `-version` output after e.g.
"VVVVVV v2.4". The build type is MAKEANDPLAY, NO_CUSTOM_LEVELS, or
NO_EDITOR (which are not necessarily mutually exclusive).

This is appended on to the end of the first line so as to not break
Ved's existing `-version` check which only checks if the beginning of
STDOUT is "VVVVVV" followed by any version number.
