Fixed text field behavior on iOS
Fixed text field behavior on iOS

On iOS, FastClick now ignores touchstart events on focused text fields.
This resolves multiple issues: double-tap to select works (was
completely broken); single-tap reliably deselects text; and single-tap
brings up context menu (previously had to tap-and-hold).
