QuickMessage system added

I always liked the idea of Toasts in Android to give a quick response to the user if something happens. Based on that idea I implemented a QuickMessage system into sqUId.

With the command UI_QuickMessage() you are now able to display a quick message to the user in the like of Android Toasts. You can define the time the message is displayed on screen or even use 0 as the time parameter which forces the user to click on the message to dismiss it.

You are also able to define where the QuickMessages will be displayed, e.g. in the bottom right corner or top centered. If multiple messages are displayed they will be stacked on top of one another.
