[GRASSGUI] CLI working again

[Michael Barton]

I got the CLI for wxgrass working again. You can type in any command (GRASS
or shell). 

Non-GRASS commands will simply be passed to the shell.

GRASS commands without arguments (e.g. g.region) will open their properties
dialogs for non-display commands. d.* commands without arguments will add a
layer to the GUI layer tree and open their respective properties dialog
(e.g., d.rast).

GRASS commands with arguments (e.g., g.region rast=elevation.10m) will be
passed to the GRASS command shell for processing. d.* commands with
arguments (e.g., d.rast elevation.10m) will display their results in the
currently selected map display. Multiple display commands separated by
commas will send overlaying graphic results to the current map display
(e.g., d.rast elevation.10m,d.vect roads color=red).
