click a tower icon

[gwho]

just like playdota.com when you click a certain tower, the info remains locked on that tower, even if you move your mouse on another tower.

quite useful when alt tabbing and stuff.

you also wont have to play "operation" by avoiding other tower icons just to have the info not change.

clicking the same icon undoes this "lock" feature, and restores mous-ing over other icons.

when an icon is clicked, a border appears so you know it's locked and locked on to a certain tower.

while in the locked state, and you click another tower icon, , it locks it onto the new tower.

I like the idea but have no clue how to implement it.
