PATHC: User32: edit control to show messages

Very small part of OS users know that they can copy text from message boxes using Ctrl+C. And those who do know, they don't like it, because sometimes it includes too much information (pasting it to IRC can lead to kicking out). That's why i have patched message box to show text in edit control. Still, some fixes are needed like:
1. getting rid of the rectangles in the end of the text,
2. increasing edit control width
3. reading value from registry to check what control should be used (static or edit)
