Initial modification of original QtMongo fork
- Modified moc parser on .pro ti been little more nicer with boost since
  still using Qt4
- Added CMake build to be the default one
- Added a FindMongoDB.cmake module from http://mgep.googlecode.com/
- Moved all sources to a proper structure src and include. Looks like
  a little bit nitpicking but make it clear to look source tree now
