Merge branch 'testing' of gitorious.org:statusnet/mainline into testing

* 'testing' of gitorious.org:statusnet/mainline:
  OStatus remote sending test cases. Doesn't actually run within PHPUnit right now, must be run from command line -- specify base URLs to two StatusNet sites that will be able to communicate with each other.
  Math_BigInteger doesn't correctly handle serialization/deserialization for a value of 0, which can end up spewing notices to output and otherwise intefering with Salmon signature setup and verification when using memcached.
  Log backtraces for non-ClientException exceptions caught at the top-level handler.
  Confirm there's actually user and domain portions of acct string before assigning things from output of explode(); avoids notice message when invalid input passed to main/xrd
  Fixing HTTP Header LRDD parsing (sites in subdirectories need this)
  Replace the "give up and dump object" attachment view fallback with a client-side redirect to the target URL, which will at least be useful.
  ignore unrecognized object types
  Pull <atom:author> info as well as <activity:actor> when we have an old-style ActivityStreams feed. This fixes subscription setup for Cliqset feeds, which currently have a bogus activity:actor/atom:id but a good atom:author/atom:uri
  Accept 'tag' and other non-http id URIs in Ostatus_profile::getActivityObjectProfileURI().
