Project Folder Structure & Naming

[Ghabry]

We are basicly just starting development again, so lets finish the organisational part :D

Some files don't use CamelCase and are completely lower, e.g. dialogfacepicker

Many classes are prefixed with Q for no real reason, imo the Q can be removed.

Put license on top of all source files

There could be also some logical grouping in folders. Most for the UI files, no idea, something like:

• database
• events (this is currently commands)
• map (all dialogs related to the map and the map tree)
• common (for commonly used stuff like Switch/Variable picker)
• [drop everything else in the src root for now]

Only with database and events in sub folders this would reduce the clutter in the src directory alot.
