Feature Request: Process multiple items in the queue at once

[x9sim9]

I find it takes about 5 instances of Fast flix running to max out my cpu usage, would be nice if I could just encode 5 files from the queue at once rather than having to have 5 copies of fast flix open and running.

@cdgriffith is this something relatively easy to do? As if you could point me in the right direction I may be able to code this feature myself? At the moment having to maintain 5 versions of fastflix at the same time splitting items between 5 different queues is becoming very tedious
