Update settings
I tried to update to KConfigXT for the automatic config management, but thinking more about it I think many settings are useless and are just making the application more difficult to use.
- Notes appearance: these settings allow to configure color and other small stuff for some special notes. This is quite useless and I think we should just use good colors for each type
- General: the system tray stuff was already removed and the only settings who still exist are the position of the basket tree and filter bar. We already have hig entries for these positions and I don't think it is a good idea to allow modifying the positions.
- Basket: the animation feature was removed, the rest is probably still valid
- new Notes: Does it do something? I tried modifying the value and the new notes weren't bigger
- Applications: sounds useful
- Version sync: sound useful but it is disabled on my install although I'm quite certain I have libgit2 installed on my computer. Needs debugging.
