Pedantic Paddlefish

Notable Changes:

• UIWidget (and all its descendants) now inherit from ElementID which inherits from Attributes. This makes traversing the child <-> parent tree a lot easier and more standardized.
• Added a Random class
• Refactored JSON
• Added i18n
• Improved the build system so objects no longer need to be listed out
• Cleaned up tags and releases
• Added logo to repo
• Fixed mouse coordinates issue with nested widgets
• Created a (rudimentary) layout loader for creating and loading GUI layouts
