[GRASS-dev] More xtnmenu stuff

[William Kyngesburye]

Another problem (in addition to what Moritz found) - it's currently  
GRASS_ADDON_ETC, not GRASS_ETC_PATH.  (and could change if we decide  
on a GRASS_XTN_PATH base path instead of multiple GRASS_ADDON_* vars)

And, for the cases where people do install addons in the GRASS  
installation, you might want to check for xtnmenu.dat in GISBASE.

Lastly, how about inserting a separator between xtnmenu.dat's, when  
there are multiple ones found?  Sortof a visual cue that they are  
from different places.
