Convert to new Swift syntax

[emartinson]

Hello, could you please convert the code to the latest Swift syntax? Can't fix some issues like
func setUpConstraints() in ADChromePullToRefreshActionView

    self.addConstraints(horizontalConstraints as [AnyObject])

gives: 'NSArray' is not implicitly convertible to '[AnyObject]'; did you mean to use 'as' to explicitly convert?

there is 'as' already. I can't get the root cause of the issue

Fixed this by replacing this with:
self.addConstraints(horizontalConstraints as! [NSLayoutConstraint])

but there are more issues with linker I can't resolve:

Undefined symbols for architecture armv7:

After a lot of time parsing swift code I've managed to fix and compile it, you may find class at https://yadi.sk/d/BqI86HDOm5qvH

Thank you very much for such a beautiful component!
