feat: Added key chording

Probably a hacky mess but oh well. Key chords can be done by
seperating binds in string with ` `. You can set the quit bind with
`quitkey`, default mod+g. (Chords also exited when pressing unbound keys).

 The config file is a list of commands. Each command should be on a new line. For example, to set the gaps you would use the <code>gaps</code> command like this <code>gaps 10</code> (make sure this is all there is on that line). This says to call the command <code>gaps</code> with the arguments of <code>10</code>. Commands can have multiple arguments and these should be separated with a space, if you want a space in one of the arguments then wrap the arg in quotes, e.g. <code>addWorkspace "1: A" 1</code>, here the arguments are <code>1: A</code> and <code>1</code>. If you want to have a quote in your argument then make sure that arg is wrapped in quotes or escape it with <code>\</code> (e.g. <code>\'</code>), to insert <code>\</code> then use <code>\\</code>. If you want to have multiple commands on the same line, e.g. binding a key to multiple commands, then use <code>;</code> as an argument on its own to separate them (tip: if you are using this for keybinds then enclose <b>all</b> the keybind commands in quotes, e.g. <code>bind mod+l "spawn i3lock ; spawn systemctl suspend"</code>).<br />

   - String rest: The command to run
+- quitkey: Sets the key to exit a key chord (note: pressing an unbound key also does this)
