Merge pull request #2 from friendica/master

IT localization updated
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.
tryout - fetch larger thumbnail if image gets streched over its size
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.
tryout - some more adjustments
Deprecate site channel.  The sys channel should be doing this.  Will fix
shortly.
privacy issue - restrictive stream permission setting with a non-targetted post cannot be enforced on remote networks. Restrict these posts to zot network.

A bit of mod/home refactoring.  This is a transient state, so it's still
messy, but it'll be much nicer after the move is finished.

pull the plug on the old location sync section of import_xchan - this has now been split off into its own function. Cross fingers because this is core functionality which was tried and true, well tested; and now it's a bit different.
Please revert this if the matrix breaks in the next few hours.
fix diaspora_retraction
bb2diaspora_itemwallwall not finding author elements - inserting empty bbcode
that won't work...
Very, very cautiously, let a developer switch to the sys chan, if
they're also an admin.
Bugger, revert - not only a dodgy cut and paste between terminals, but
also pushed to the wrong repo
provide a way to sync locations and get rid of bogus hublocs, now implemented
