New test binary.

• fix: widget editor page number was in the wrong location for portrait mode
• button positioning can be changed by the user

Screenshot code was moved out of the ASUI binary and into a script (not included with this test) that is launched by ASUI. So if you want to test the button editor and don't care about screenshots for a day or two...

Rotation buttons can be moved but not to the secondary page. Landscape and portrait also share the same layout.
