added powerline symbols for the unicode fonts

Hopefully this is a start. This is the first time I've modified a font though so I'm not too sure if I did it right. Only problem is the 14pt have a even height so there isn't a 1px point on the tip of the arrow without making the character top or bottom heavy.

So I've been looking through the diffs and there's a bunch of stuff I changed without knowing it. I'm going to go ahead and leave this open but open a issue on it because I doubt you want to merge this.
