Make HTTP timeout configurable on OStatus's remote-tests.php (needs to be pumped up a fair amount when doing Salmon pings with queues off on the test boxes, especially without the fast math library)

* update translator documentation.

Fix ticket #2829: we have more subdirs to pull than just avatars now; updated the upgrade directions.

Fix for ticket #2828, part II: apostrophe in site name set in installer created a broken config.php.

The previous commit fixed the base installer to properly quote its strings when creating config.php... but you'd actually end up with double-escaping if you had magic_quotes_gpc on. Magic quotes are evil and lame, but we gotta deal with em. :P Updated the web installer code to check for magic quotes, and to grab its variables consistently through the same interface.

Now running values through var_export() before putting them into the config.php, ensuring strings will be properly quoted.

Clean up remote avatar temporary files if we fail before saving them into avatars directory (OMB core, OStatus, WikiHowProfile, YammerImport)

ModHelper -> silence only, don't let them sandbox (it's too confusing atm without a good audit trail)
