Macro Keybindings

- Server crash is fixed (this means the mod doesnt need to removed anymore from the server mods folder)

- Implemented support for multiple sets of macros (I had to change the json structure, so please BACKUP the old config just in case.) This includes:

- Hotkeys (pageup and pagedown) to quickly change between them ingame

- Buttons in editor GUI to change between macros

- Buttons in editor GUI to add and remove full macro sets

- 'Save' button that saves the macros currently displayed in the text fields (DO NOTE, moving to another macro set without hitting 'Save' will discard the changes)
