correct color handling
SGR 255 bg & fg color support
fixing lint missing semicolumns
fix ansi output, test fg === null instead of relying on fg to be true (fails if fg = 0)
use correct values for bufferswitching
OSC does not need to have semicolumn, it can work with just 1 value
Gotta merge 'em all! Merge branch 'master' of jedi4ever/terminal.js
