Soprano 2.2.2 released

[Sebastian Trüg]

Soprano 2.2.2 is a maintenance release which mostly improves the build system 
which should make things easier for packagers.

 * Properly clear the error in the SparqlModel
 * Made all D-Bus dependant parts optional for successful compilation on
   Windows.
 * Redland include dir fix.
 * New cmake options to manually disable all optional components:
   o Redland backend
   o Sesame2 backend
   o Raptor parser/serializer
   o CLucene full text index
   o D-Bus integration
   o Apidox generation
 * Less use of dynamic_cast
