Move calendar handling out-of-process

Browse Source 
Unfortunately the evolution-data-server client-side libraries seem to
block the calling thread. This is a major problem as we must never
ever block the main thread (doing so causes animations to flicker
etc.). In the worst case, this problem causes login to hang (without
falling back to fall-back mode) and in the best case it slows down
login until a network connection is acquired.

Additionally, in order to sanely use these evolution-data-server
libraries, GConf has to be involved and GConf is not thread-safe. So
it's not really feasible just moving the code to a separate
thread. Therefore, move all calendar IO out of process and use a
simple (and private) D-Bus interface for the shell to communicate with
the out-of-process helper.

For simplification, remove existing in-process code since internal
interfaces have been slightly revised. This means that the shell is no
longer using any native code for drawing the calendar dropdown.
