Issue #590: Linked conversation titles to source. 

If a theme wants to have it different, it can always copy this .tpl file to ../theme/tpl/. I didn't commit this directly, because it's a little bit controversial. But I like it!

some backend work for the remaining missing bits of mod_hubman - this is still a fair ways from being complete and is not ready for prime time. Basically we'll let a channel send out a public message saying "these are my currently approved locations" and anything that isn't in the list will be marked deleted. We'll send out this message when locations change somehow - either through direct personal involvement (hub revoke, change primary, channel import) or during a system rename or "find bad/obsolete hublocs" activity. This way we won't have clones sending back location info we just got rid of and re-importing the bad entries.

more heavy lifting on the hubloc management and revocation infrastructure; don't rush me. This is going to become a fundamental part of zot. It deserves careful consideration.

Made link post titles to source optional in display settings. Hopefully I did a right.
Thanks to Thomas other people see now your posts on your channel page also linked to source. If enabled.
