Returning the EasyTipView created by the class "show" functions

[shuetrim]

I have been using EasyTipView to implement a demo system within the app. It works well but I found that creating the tipview and then showing it caused dismissal to not trigger the onDismiss delegate. To get around this, I have used the class show functions. When the tip is dismissed, the delegate method is called, which is great. However, I then have no way to dismiss a tip using the dismiss function within my own code. To address this, I simply altered the code to return the EasyTipView from the class functions. It seems to work well. I will try to put a pull request in place to make the change available if you wish to include it.

Thanks for making the code available!
