0.5.0 - ANSI color escape code support

I got asked to do the ANSI escape codes for color because Wahlolly couldn't find a way to get them to work. This involved making some kind of TTY, and let me be clear, i didn't know it would be so tedious to develop one. This implementation has support for dark and bright colors by using a color palette. There isn't 8-bit and 24-bit color yet, nor is there a shell parser, so please wait a bit more when it gets implemented.
