Defect:

In fullscreen mode, when the adventure window size does not fill the entire monitor (leaving black bars on each side), mouse movement is ignored in these areas. This results in difficulty scrolling the map in fullscreen mode, since you have to be exactly within [0,15] of the edge of the adventure window.

Fix:
Have the adventure map element, CAdvMapInt, subscribe to all mouse move events by setting the `strongInterest` bool to true. This will extend the scroll region to [min, 15], eliminating the dead mouse move space on the side of the window.

Notes:
Impacts adventure window mouse move event handling. Manually validated the scrolling the map now works without having to precisely aim for the edge of the window.
