Not gonna merge this one for a few reasons

1. The code is still a buggy mess
2. I like the console to be as clean as possible, like every other language's console
3. All the colourisation and calculations and stuff happening on the console is, ultimately, going to affect the performance of the console
4. I'm too lazy to fix all the bugs I want to move on with the rest of the actually important features of this project

I'll merge when I have to though
