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.
