Tobias Doerffel 1d5cb23385 File and class renames part 1
Most files and most of the core classes and their methods have been
renamed to match new coding style conventions:

391 files changed, 25400 insertions(+), 25598 deletions(-)

Furthermore splitted some files where model and view classes were
declared or implemented together in the same file.

Should be tested thoroughly as I might have missed renaming some virtual
methods or SIGNAL/SLOT parameters.
