some updates to snapshot site?

[Guenter Knauf <fu...@apache.org>]

All,
I just wanted to point someone to a recent snapshot of 2.2 branch, but
found that there is none; we only have 2.0 branch and HEAD ...
I think it would make sense to add 2.2 branch snapshots.
Also when on that topic: we have apr/apr-util snapshots of 0.9 and 1.0
branch, but none of 1.2 / 1.3 / 1.4; wouldnt it make sense to at least
drop 1.0, and replace with 1.3 now?
Same for apr-iconv where we have 0.9 and 1.0, but no 1.2 branch ...

Günter.
