Update Bolt compatability to 3.7

[Maelstromeous]

Hi JarJak,

Just tried installing your extension but unfortunately Bolt won't let me install it via the extension panel as I believe your extension requires Bolt 3.6, whereas the newest version (and what I'm developing from) is 3.7, therefore Bolt is chucking it out.

If you're able to update your deps that'd be fab! Cheers in advance.
