now locations and mapsets are not sorted in alphabetical order.

not for, but not strongly against, however:
- The EPSG database and proj.4 are likely to be updated more often than
GRASS is.
- packagers should set --with-proj-share=, ./configure should give a
clear error message if not found for home-brew. Tcl then finds this dir
in the "PROJSHARE" variable.

yes please, and auto-fill the highlighted value in the create dialogue.
