Unit-only attack move not working

[snelius]

When given attack move command for the selected group of units (Ctrl + Q + Right Click with unit(s) selected) they should go to the given point attacking enemies on their way. Functionality is not working in a24. Tested on revision 24725.

Confirmed. Caused by my hotkey fixes, because now one can't have both attackmove and attackmoveunit active at the same time, since the latter is more specific. (the thing is that "attackmoveunit" is a modifier to attackmove, not actually considered equivalent to attackmove). You can fix it by setting "attackmoveunit" to another hotkey that doesn't conflict with attackmove. However, since putting "A" would rotate the camera, it's probably not the best call.

I think the solution, which needs a few C++ changes, is to make "attackmove" also register on "Ctrl+A"

In 24752:

Fix unit-only Attack move.

attackmoveUnit is more specific than attackMove, so since rP24675 won't fire at the same time. However the GUI code expected that, breaking it.

Instead, properly check for either attackmove or attackmoveUnit.

Also fix an issue with rP24675 where hotkeys would be release if switching to a more specific combination of the same hotkey.
