Should bring up WiFi when ppp fails

[adrianmay]

My server lives in the garage and runs create_ap. Sometimes the ppp fails and sometimes the WiFi does. If the ppp works I can use my phone over 3g to ssh to my static IP and diagnose the problem. If not, I have to physically take a keyboard and monitor down to the garage to find out what's up. Usually, the reason the WiFi fails is that the ppp did and create_ap made no attempt to bring up the WiFi thereafter. If it did, I wouldn't need to drag peripherals around ever again because it would be incredibly unlikely for both ppp and WiFi to fail at the same time.
