refactor(Mastermind): refactor into HeistEditor

[xesdoog]

BREAKING CHANGE

• Fully rewrote the heist editor. It is currently a test prototype that will eventually serve as an extensible base where plugging in new heists and/or jobs would only require editing a data table.
• Completely overhauled the keybinding system by moving all logic to a Keybind object that stores and manages controller and keyboard keybinds simultaneously. This change however makes all previously saved simple keybinds useless; therefore deleting the ssv2.json config file is recommended.
• All toggleable features created using the AddBoolCommand and AddLoopedCommand Tab methods now have an options button by default. This button opens a context menu that lets users set a quick toggle keybind (turns the feature on/off) as well as any other context logic the feature wants to draw (tweaks, preferences, etc.).
• All keybinds now support an optional modifier key (ex: SHIFT + F12).
• Fixed a programmer error that prevented the script from loading in YimLuaAPI.
• Fixed a few other bugs.
• Implemented SoloMissions thanks to @TCRoid
• Refactored and integrated MiniGameHack thanks to @sch-lda
