Subject: Major change in the way inventory is downloaded: added a method
 throughout IIventoryService that fetches sets of folders at once. Also added
 folder id in the InventoryCollection data structure, so that we don't need to
 go to inventory server again just for that. This reduces the chatter between
 sims and inventory server by... a lot. On my tests, this reduces initial
 inventory download down to 30% of what it currently is.
