Immediately update the EditText contents when the emojicon size is changed.

I have no problem changing it be written like that, although I do appreciate the common practice of having a single exit point in (most) methods.  Plus, having the ability to specify "?w=1" at the end of the link to the diff to ignore whitespace differences takes care of any problems with reviews.

That said, if you still insist on having the code return early to avoid the indentation, I'll make the change.
