  m.proj: replace checks in code by parser rules (#106)

This simplifies the code and translations and standardizes the messages,
but it also allows m.proj in command line to start GUI as all the other
modules do without an explicit --ui.

All checks are replaced by rules except the overwrite check which is checked by the parser itself.
