Moving all websocket communications out of the read thread callbacks (now async). Fixing threading issues with prontserve.

Breaks Tabbed mode for now

Cleanup whitespaces

Switching prontserve add_job file uploads from string concatination to array appending for a 4x speed up (well, a 4x improvement according to pycallgraph on a 1.75Ghz Core i5. Possibly more on a rasperry pi.)

Removed all the unused slots and fallback to Cython.
