i updated d.m/vector.tcl that it can handle multiple categories. the 
problem is, that the categories are hard-coded (the icons aren't 
anymore, they are selected with a GSelect window) and i haven't figured 
out how to have them updated without having to change the source code. 
i hope that a can upload the changes to cvs next week that you can have 
a look at them.

although d.vect works again, there is one issue left. with the current 
selector, the icons are limited to those in the basic directory. as the 
items on the list created by the new function are something like 
"basic/icon", d.vect doesn't accept for example "demo/icon" anymore as 
the "demo" directory doesn't appear anywhere on the possible list.
thus, this version of d.vect doesn't properly work with my changes to 
vector.tcl or a cli call of d.vect as they both allow the use of other 
symbol directories than "basic".
for now, that doesn't really matter as there is are no other symbols as 
those in basic (at least officially, who know what guys have on there 
hard drives) but once there are more symbol collections this issue has 
to be addressed.
