Use Horde_Registry#appInit() in horde-translation

Otherwise, this fails when retrieving version information for
applications that use $injector or $registry in their _bootstrap()
methods (i.e. IMP 6.2).

I'm assuming the only reason we haven't updated to using appInit() is
because it simply wasn't needed before now - the application just worked.
(AFAICT, horde-translation previouslt required a working version of Horde
installed, so this doesn't change anything).
Don't include SmartLists on the Task form.
Better status codes for PING request when the state disappears.
Merge branch 'master' into horde_5_2
