1) Currently at some cases like ordering units to move, gatther, return resources, attack, using hotkeys to modifyif one uses hotkey to change mouse action RIGHT click is usneeded to execute action and LEFT to cancelit.
But in case of placing buildings, preselected actions using buttons it is LEFT click executing action and RIGHT click to cancel
This behaviour is both non intuitive and not consistent
This patch is unifying mouse behaviour to RIGHT click to execute action and LEFT click to cancel and execute selection as it is now
TODO:2) If someone uses command button to modify mouse action LEFT click is needed to execute it.
update manual page3) As default click to execute most of the not modified actions (walk, gather, repair, ... ) is RIGHT click, this patch is switching behaviour for point 2.
