v0.6.0

A pretty big update. I changed the library I use to parse escape sequences, and now I'm able to provide a lot more semantic information about sequences. I also spent a lot of time improving the UX; we now print text with the correct foreground+background colour in the web UI, use icons for common sequences, and generally try to display sequences in a more succinct way. I think it's now a lot easier to follow+understand complex terminal output in Escape Artist.

There are probably a few rough edges remaining, but I wanted to get this published before the weekend ends b/c I'm pretty busy with my new job during the week.. I'll try to do some more polish soon.

Main code change: #7

Full Changelog: v0.5.10...v0.6.0
