Trying to port installer_thread to another process to speed things up
Fixed mutex in slides.py
changed mutex var name to lock. Clear wasn't working, needs testing now
Don't know how to clear a Multiprocessing.Queue
My country mirrors are worthless, removed country based mirrorlist generation.
The "too many events" problem still persists. I try to mask it deleting the old events
Renamed installation_thread to installation_process. NOT TESTED
