Stable horde's "2 per 1 second" throttle blocks batches larger than 2 and X/Y plots

[axemaster]

The API added a throttle and and broke this UI's batch and (multi*) X/Y plot features. Obvious work around is to put in a delay between submitting jobs. submit 2 and wait a second etc. until they are all queued. If that's how it works.

I consider this a design bug in the current function though it's a retroactive one.
