Subject: [PATCH] ChannelFeed now marked as an abstract class

The ChannelFeed class has always been considered as an abstract class.
Looks like we forgot to update its definition since PHP switched to
support class abstractions.

Also marked abstract the three inner methods that must be extended:

 ChannelFeed::outHeader()
 ChannelFeed::outItem()
 ChannelFeed::outFooter()
