Command Execution!

This release adds support for terminal command execution, parsing of ANSI color escape sequences, and bypassing of Chroma's syntax highlighting to do our own custom highlighting matching the colors coming from your terminal. It also includes support for theme aware colors, so if the command your executing supports them you will see different colors based on the theme you have selected just like you would in a real terminal.

Full Changelog: v0.5.1...v0.6.0
