Simplify autogen.sh

[Stef Walter <stefw gnome org>]

Currently autogen.sh requires that you first git submodule init. Failure
to do 'git submodule init' gives a cryptic error about a missing
Makefile.in.

To make it easier for people to start, empathy does the submodule stuff
in autogen.sh.

Here's a patch which implements that. Is there a bugzilla or something,
or is posting patches here the best way?

Cheers,

Stef
