Store Keybinds in DB as Unicode instead of plaintext

[broxen]

Summary

Current keybinds are stored in the database as plaintext inside of a json blob. This winds up with potentially dangerous text combinations such as:

                        {
                            "Key": 39,
                            "Mods": 0,
                            "KeyString": ";",
                            "Command": "show chat$$slashchat",
                            "IsSecondary": true
                        },
                        {
                            "Key": 40,
                            "Mods": 0,
                            "KeyString": "'",
                            "Command": "quickchat",
                            "IsSecondary": false
                        },

As ; and ' are special characters in SQL queries, it would be best to store ; and ', or any KeyString, as unicode (UTF-8?) point values to prevent any potential issues \u003B
