[sabayon] Proposed change to the "details" window

[William Lachance <wrlach gmail com>]

Hi,

I've been playing around with the idea of modifying the "Details"
window in Sabayon to be more useful, and came up with the following
mockup (try not to get too bogged down in the details: I know the
labelling is kind of ugly, for example):

Fairly self explanatory, I think. Each revision to the profile can be
toggled "on" or "off" and moved up or down in precedence (to handle the
case where a setting is toggled "off" in one profile, and "on" in
another). Within each profile, you can set stuff to be ignored or
mandatory much as you would when editing stuff in the Xnest window (one
important difference is that "ignore" settings wouldn't be discarded).

I _think_ it should be possible to implement this without making too
many changes to Sabayon proper.. based on the results of this evening's
hacking/investigation, the main challenge seems to be regenerating the
actual changeset information from the mess of files contained within
the profile .zip. This probably involves some changes to the way
delegate classes work. 

Then again, I'm still a bit of a newbie to the Sabayon codebase, so I
might be missing something. I also haven't completely convinced myself
that my UI proposal in sane. :-) Anyone care to comment before I go off
and start ripping things apart?
