HTML/man docs and GUIs should now show opt->key_desc if it exists.

e.g. makes v.mkgrid's help page and GUI options much easier to figure out.

applied to 6.0.x and 6.1 cvs branches. please test!


TODO: (by someone who knows some TCL)
Edit lib/gis/gui.tcl so that the option description in the GUI indicates if
multiple answers are ok.

e.g.  (string[,string,...]; required)

or something like that.

"mult" = 0 or 1 is already there, just need to test & append the string.
