more stability/recoverability changes

Split try block for exporting the different feed types (so failure on one doesn't block the other)
Converted the Producer to put a static True value on the queue instead (prevent possible overflow)
Add jingles:frequency option
Now resets counter to prevent eventual overflow
Add saving of status file to record current position
Add reading of status file on station init to restart where it left off
Reset the counter when incremented to prevent overflows
When a new playlist is detected (ie, songs added/removed) playback attempts to keep going instead of restarting
