shaves off ~15% of the load time of Qt 4.6.

findProFileFor(), buildDir() and createProFileReader() make sense only
in relation with an actual pro file anyway, so move them there.

Should fix a lot of corner cases, might introduce a few bugs.
Also rename functions/slots to be better named.

Generic Project Manager and CMake Project Manager are missing from this
patch.

Move the code that compares the Qt version's debug|release property
with the build configuration's debug|release property
to the new build configuration class.

Note: I didn't fix all the connects and there are a few missing things.
This compiles, more work is coming.

- Move the s60devicerunconfigurationwidget into a separate file,
  add an info button that connects to the device and displays
  CPU/Trk version for testing the connection.
- give TrkLauncher a parent object and an acessor for the device
  description in formatted form.
- Break deadlock when trying to terminate the Windows Trk writer
  thread with bytes pending by using a wait with timeout and
  termination flag.
