Fix two documentation warnings.

The crossdomain doc was named *.xml instead of *.rst causing it to not
get built or included in the toctree where it was supposed to.

The apache deployment guide wasn't linked to from anywhere, so I added
it under the normal deployment guide.

Set TZ environment variable to avoid a stat call

By setting the TZ environment variable for the WSGI process we avoid
the stat("/etc/localtime") on every request handled that logs using
strftime().
