[PATCH] Add 0ad, Add 0ad-data

[ng0]

This is a snapshot of my progress. This means anyone who feels like fixing what 
I commented
can pick it up and finish it. If there has been no progress or repost of any 
kind, I will
pick it up in a week, a month or half year or whenever I feel like next time to 
work on it.

I have no real motivation to finish this as I play games only very rarely these 
days.

What needs to be done:
- 0ad-data: fix up description + synopsis

- 0ad:
  - unbundle the patched mozjs
    or
  - make the bundled mozjs build
