[GRASS5] Wishes and GUI code cleanup patch

[Cedric Shock]

Hi,

If anyone else has any wishes for the generic GUI, now is a good time to kick 
them around here.

Excellent idea. I'm already considering adding something like 
$(GISBASE)/etc/icon that will be looked in for an icon for individual 
commands (named something like r.in.gdal-.gif). I haven't put very much 
thought into it yet. If/when I get there I'll check for generic icons too, 
like r.in-.gif or r-.gif. I'm also planning on hijacking some of those nice 
icons from Michael's work to use for some open existing prompts instead of 
">".

I'm trying simple, more conventional layouts first. That (string; required) 
stuff is definitely going to get right-justified at the least. A tree that 
starts with only required options expanded by default and an expand all 
button would definitely be something a gui could do.

Do you mean window size (which would be a gui side thing) or loading options 
(which could be a parser thing, a gui thing, or even a third party thing)? 
I'm nowhere near this sort of step yet, but having the parser still parse the 
options when the gui command line switches are used seems like a compelling 
idea and would make it easy for third party utilities to open the gui with 
specific options selected already.
