Adding finance and gis as primary categories

[Frank Schima]

Are there any objections to me adding "finance" as a primary category  
- i.e. a new directory under dports? In particular I'm thinking of it  
for the proposed new port for ledger [1].

Also, a "gis" primary category would be good for MapServer [2], GRASS  
(should that ever happen) and probably a few more.
