Fixes: Move Buildparser to the projectexplorer, use in cmakeplugin
Details: This enables us to parse the build errors correctly. The makesteps of the qt4project and cmakeproject have some code dupliaction, which could be refactored. And the code to find out the correct build parser could probably also be done better, but we are now parsing the build output for cmake.
