Lots of documentation updates.

We had a lot of http links pointing to the old domain. They should
all now be properly updated to the new domain. (only bazaar-vcs.org
entry left is for pqm, which seems to still reside at the old url.)

Also removed one 'TODO' doc entry about switching to binary xdelta, since
we basically did just that with groupcompress.
