Strip whitespace and empty lines from the cheat editor. 

Previously, bsnes would turn the cheat text into a list of cheats by splitting
on '\n', producing an empty "cheat" after the last line of the editor:

    "7e0003=00\n".split("\n") -> ["7e0003=00", ""]

That empty "cheat" is not a valid cheat, so the result would be marked invalid.
Teaching bsnes to silently skip empty lines worked, but it would preserve
multiple blank lines between two cheats, which was silly.

Now we iterate over all the lines of the cheat editor, putting valid codes in a
new vector, and setting a flag for invalid codes.

Fixes #63.
