Title: Prevent spurious newline insertion into UITextView on focus.

Hi, we encountered the same issue that's discussed here:

http://stackoverflow.com/questions/21077842/uitextview-adding-new-line-unintentionally

Apparently it's an iOS issue - have implemented the suggested fix on our fork and it has solved the issue for us.
