Default Module: Editor Screen

[voylin]

The default editor screen still has some work and won't be finished very early on because of following to-do's:

• [x] UI;
• [ ] Zen-mode UI;
• [x] Default positions for modules;
• [ ] Possibility to change module locations;
• [ ] Way to add completely custom module types to the editor layout;
• [ ] Tabs + Containers;
• [x] Save system to save changes + split offsets;
• [x] Hide empty tabs;

Design plans are inside of the /assets/design folder of the project

Part of this was handled in #55 but still too many basic features are missing for this to be marked as compelete for now

Closing this issue in favor of #63
