o Fixed bug where the commander UI buttons would not function (select all, go to requests, etc)
AvHTechTree::GetIsMessageAvailable would not return true because no tech tree nodes would be found for these messages. I inserted a check to bypass the node checking for these messages. It's a hack, but since they're already hacked into the TechNode code, it should do for now.
