[Catalyst] Road Map doc complete

[Nathan Waddell]

I've completed the Road Map, found at:
http://catwiki.toeat.com/fromtrac/future/roadmap.highlight.

Please take a look at it and point out any glaring typos/errors, etc.

Interestingly, I was able to make only a few changes to the changelog
for the current version of Catalyst in order to create the nice
formatting. I'd like to suggest changing the formatting of the header
line in the changelogs going forward:

5.7012  2007-12-16 23:44:00

to

### 5.7012 (Released on 2007-12-16 23:44:00)

Anyway, enjoy.
