Change `Button` to owner drawn class

[compnerd]

Convert the Button implementation to use an owner drawn button. This should allow for changing the button to include an image and title simultaneously. Additionally, it would allow for embedding a Label and ImageView members which can then be made available to the user to control the button more thoroughly.

Last few days I am playing with BS_OWNERDRAW on Button, and while my drawing code works (for background, border and text colors), I am having issues with passing Button ref to the WndProc which handles the drawing of the Button.

I can't promise anything at the moment.

Ah, you mean the reference to the Button instance? You cannot do that directly; the way to accomplish that is by squirreling away the pointer into GWLP_USERDATA. There are a couple of examples of that in the tree already.
