Automated Ottawa DTV Scanner Tweets Updates

[teknick]

For those of you who are interested, I've made a script that tweets any changes in OTA channels to @OttawaOTA.
Scans are done hourly when I'm not using the tuner. It's rudimentary and prone to failure, but I'll keep it up as much as possible.
It also doesn't filter out existing distant stations that may pop in and out. I'll maybe do that tomorrow.
