Text input windoe

This isn't ready for being merged in but I just want to know what people think of this idea.

This window will replace the dialog box that is thrown up by windows for text input. It takes the same inputs as the previous text input box and has the same outputs so it should be a drop in replacement. I've kind of not used the text input event correctly for my new window as its not in the same format as would be expected. This may cause issues but it should be fine. 

If you want to test it I have only enabled it for the staff rename so far.
