citra_qt: Implement UI for adding/editing/deleting cheats

Browse Source 
The UI file is rewritten, to better make use of Qt's layouts (instead of depending on abstract geometry). "Add Cheat", "Save", "Delete" buttons are also added.

The UI logic should be rather easy and usable (IMO), but the code may seem a bit dirty. If anyone has a better idea regarding UI logic design or code implementation, feel free to tell me about it.
