◱ PixelyIon 75d485a9a7 Addition of Controller Configuration UI
This commit adds in the UI for Controller Configuration to Settings, in addition to introducing the storage and loading of aforementioned configurations to a file that can be saved/loaded at runtime. This commit also fixes updating of individual fields in Settings when changed from an external activity.
