Finally done and dusted the core of what v5.0 was supposed to be. Now all that's left is to re-implement the couple missing features and that's gonna be a full release. For now, it's a beta.

Changelog

• User interface layout and resource pack sprite rearrangement
• User interface is now customizable via resource packs (sprites and textures)
• "Settings" interface has been moved to a separate tab
• Removed "File > New" for now. No point in having it when there's no editing capabilities

API Changelog

• The "Tabbed Document Interface" now supports having different "types" of tabs. For example one type could be dedicated to showing statistics data, while another could be dedicated to showing a "Settings" interface, etc.
