Content rescaling on layout (orientation) change

Hi, Thanks for the great work! :)

I just found if I rotate the device then the token field's scroll view content size not follows its frame change, which implies the inputTextField's width also not resized.
Do you know a more convenience method to fix this than my layoutSubviews override?

Cheers
I'm finding that in my app, with this change we're running into issues where the token field can't be collapsed. I was seeing this in the example app too. The inputTextField now gets stuck in a state where it will not yield first responder. I'll investigate more into exactly why this seems to be an issue.
