added a running thread check when starting a ping to be sure a tab doesn't duplicate
I think I got the start/stop toggle working as intended
Merge remote-tracking branch 'origin/regui' into regui

Conflicts:
	pingpung/newmain.py
stopped trying to get colors working for now, instead switched to uic module so gui objects can be rendered from .ui on launch
removed the two startup tabs in designer that I had been removing in code
cleanup and got tests running and deleted old pingpung.py (may she live on forever in our commit logs)
comitting in a broken state as I'm out of time
