Separated time related stuff into a new file, time_Ambiant.
Does all the functions such as curHour() and timeStr(numb)
I did this because I realized I'll probably be making reference
to it across several classes.

Cleaned up and formatted comments in songQ.py

Reworked songQ.py and scheduler.py to make use of the new
time_Ambiant.py file properly.

Okay and with all that said I haven't been able to really test anything
so there's probably bugs in here that I need to come back to find.
