checkAuthorship events, Ostatus_profile rewrite to handle it

Lost dependency of OStatus plugin for lib/microappplugin.php, whoo!

also noting which plugins should be upgraded to new saveActivity support.

Favorite plugin won't work with the new system just yet, it doesn't have
the necessary functions to extract activity objects, but that's coming
in the next (few) commits.
