Move configuration out of feed_parser.php

Ultimately the goal is to be able to have multiple feeds configured, each of which has:

• Youtube user name / url
• Title (for the output xml feed)
• Description (for the xml feed)
• Link (url for more info about the podcast)
• itunes image (for the xml feed)
• Feed Output name (where the podcast will be output - name.xml)

Could be reading these out of a directory, or yaml files, or even just defining a config.php where an array of these gets defined.

Then we could walk through that array, calling feed_parser.php for each of these feeds and saving the file out to disk.

Of course this way you can't refresh just one feed, unless perhaps we add a feed ID, and then you could pass in a feed ID and we could just refresh that one.

In the interim the approach I've taken is just to copy feed_parser.php and rename it for each individual podcast I want to create, and then in the cron job point each feed to a different output xml.
