Move CleanerTableModel to its own file

models.h / .cpp was getting too big (around 2.5k lines), and each change
triggered a rebuild in tons of parts of Subsurface, this is the first
commit trying to make the models code sane by removing them all of the
models.h/cpp file and also clearning code in the process.
