WPF Message Boxes

[grymmjack]

This is not something new. This is something I made a long time ago that I may or may not be trying to work on again. I like message boxes. Always have. Especially customizable ones. These are highly customizable and can replace the built-in error message boxes in QB64.

Really nifty @spriggsyspriggs - I've never seen anything using that new WPF stuff like this before from any language.
