Feature Request: Search nearby structures menu item

[Bluscream]

It would be super cool to have a command that would instruct selected units to go through all houses nearby (in cities etc). It can be quite annoying to have to go through each house in a city alone by hand and most often i just end up switching to zeus and mark the houses with hostily units once i finished clearing the streets. This feature would also be a great preparation to showing off the enhanced AI pathfinding in the upcoming addon once it's finished. and until then it just takes a burden of me :3
