Thanks Larry,
I have pushed that to the master. The library should make it possible
to run GRASS modules without mapset and data data import. You can try
to run a GRASS module in this mode  from GRASS Tools ( which is now
always enabled), if no mapset is open. Most probably it will need more
fixes on Mac and Win. It is work in progress, currently there are only
few modules and you can find problems.

I'll write more about in another thread soon.
