[GRASS5] r.support - initial parser added

[Andreas Lange]

Hi Markus,

just an idea: 
Why not keep the old module with inter and create a new one from the
code in a new cmd dir?
This should be the standard way of implementing both interactive and
commandline modules. See e. g. r.neighbors for an example.
One could argue if this is really efficient, as the code will somewhat
doubled. But it works.
The commandline parameters are usually controlled with the G_parser
call. If you call "r.support" you will be switched to interactive, if
calling "r.support something" you will be switched to commandline
module.

HTH,

Andreas
