Multiple construction queue manipulation screen

[ekolis]

What do you want to see?
A screen that allows you to manipulate multiple construction queues at once.

Things that it could do:

• Toggle flags for queues: on hold, emergency build, repeat orders
• Add items to the beginning or end of the queues (specify which first)
• Clear the queues

Things that it couldn't do:

• View existing queued items (except in aggregate, e.g. min/max/avg ETA)
• View build rate (again, except in aggregate)
• Reorder specific items in queues (except perhaps generically, e.g. "the first item in each queue")
• Remove specific items from queues (except perhaps generically, e.g. "the first item in each queue")

How would it help players?
Make construction queue management much easier when dealing with large numbers of queues
