FAQ on the Ubuntu release process

[Matt Zimmerman]

After responding to a flurry of last-minute feature requests for Dapper, I
found the gumption to tackle a long-standing todo item: write a FAQ about
why we do things the way we do.

The result is: https://wiki.ubuntu.com/TimeBasedReleases

The content is a reasonable first draft, but it looks fairly awful.  I would
appreciate proofreading, feedback and formatting improvements from the
documentation team.

Thanks,
