Improvements to text display. 

Starfighter uses an absurdly crude method for wrapping text which
basically fails very frequently when large words are chosen. The only
reason it got away with it is because text strings don't vary. Well,
I've been quite annoyed by having to test for this and rework my
text so much, so I've added in a secondary system: if it's really
close to the edge, and the next three characters are going to be
letters, it adds a hyphen and moves on to the next line. This still
isn't 100% fool-proof, but it should catch most problems.

Also removed the "temp fix" which shifted the letters by a pixel in
code, and just shifted them in the actual image. I don't understand
why the "temp fix" was there in the first place, to be honest.
