games-strategy/0ad: bump to 0.0.24b_alpha

Huge thanks to everybody mentioned in this commit
(and likely others too, sorry if I forgot you!)

This started with Arfrever giving an initial bump,
then several revisions later, we seem to be in a position
where it's fully working!

Most of the issues came from (de)bundling SpiderMonkey
and NVTT:

* New SpiderMonkey releases regularly break the APIs
  which 0ad uses, so we're reverting to the bundled
  copy per upstream advice;

* NVTT has been abandoned upstream (as an independent project)
  so the 0ad developers have taken it over and applied significant
  patches. We use the bundled copy now to take advantage of these
  fixes.

We also abandon 0ad-data for now. We're now using the released
asset files for 0.0.24b_alpha but the 0ad ebuild itself, thanks to
Wolf-Dieter, can now generate these assets rather than relying
on a separate ebuild like 0ad-data. This simplifies matters.
