commit d6a9dc69c0024e196f5d610e6cf7bcd9df6a5c82
Author: Matthew Barnes <mbarnes redhat com>

ECalClient: Follow up on a timezone-related FIXME comment.
Emit the "timezone-added" signal from an idle callback on ECalClient's
GMainContext, instead of from whichever thread the timezone was added.
This makes life easier for any handlers of that signal.
Still need to address a similar FIXME comment in ECalBackend, but that
will have to wait until after the backend API rewrite.
