Migrate to Boost.Signals2 from Boost.Signals
Boost.Signals was deprecated and is not improved further.
This patch removes Boost.Signals from 3rdParty and adds
Boost.Signals2 and its dependencies.
Also removed the Qt signals compatibility file
Swiften/Base/boost_bsignals.h.
Test-Information:
Build and ran unit tests on OS X 10.11.4. Confirmed successful
login using Swift client.
