Editing Code Review

Editing code was reviewed to fix it and to make possible to add custom tools for the selected shapes that makes sense. But the code did not work that right because of separation between editing component and actual mouse handling (like face picking functionality). Also, those tools will paint everything in a custom document, meaning that they can bring a lot of functionality in a consistent way without letting things trailing in the actual document, and also is based completely on NaroCAD code, which gives another good things to work on). I will hopefully soon make a concept that works and I will show the progress as soon as possible.
