Un-style when backspacing

[wmertens]

I made something italic and then backspaced to correct the word, but then I couldn't escape italic any more… maybe backspacing should remove the hidden terminating character, thus showing the starting character again, and un-style the range?

This definitely seems like a sensible enhancement, the way this work right now is a bit annoying.

Maybe the right way to do this too would be to "unsticky" the inline styles like discussed here: facebookarchive/draft-js#430
