Caret position wrong with variable font width

[tobbi]

If I have bold text which is slightly wider than normal text, the caret position is off by a few pixels, especially when having a lot of text (because the wrong offsets add up).

Most of monospace fonts have same width for bold text.
Ace tests if font supports bold text and adds .ace_nobold class if it doesn't.
You can use that as a workaround until #460 is fixed.
