Implement a debugger

[aapoalas]

Well this is certainly a "small" task! No worries, you just need to figure out how to make the bytecode interpreter pause and spin, while communicating with a DevTools client. Choose either Chromium's or Firefox's DevTools protocol for the communication for best effect. Personally, I like Chromium's DevTools more for debugging and performance analysis but Firefox's is better for some things, and easier to "get behind of" so to say.
