[GRASS5] DB default settings now defined in new mapset

[Markus Neteler]

Hi again,

update:

I have fixed the lack of default DBF DB settings when
creating a new mapset. Now both the text interface and the
GUI create the dbf/ directory in a newly created mapset 
and generate a new VAR file which contains the default DB
settings to DBF.

Fixed again in both 6.0-CVS (for 6.0.2) and 6.1-CVS.

A user can certainly modify the settings with db.connect as
before.

cheers

 Markus
