Channel per user and channel per node

I think this module could easily be expanded to permit each user have its own channel (for tracking, or just to pay a share of the revenue to your writers), the channel could be made part of the user profile.

Additionally I think it would be easy to enter a channel "per node" using a functionality similar to "nodewords", i.e. the poster could enter a channel in the node creation/edition time.

The whole process could be made as if the poster did not enter the channel when creating a node, it could take the one in the user profile, if there are not one defined, the node could use the default defined in the module setings.

This change could me made that each node will have its channel-id stored in a table (if user or node channel are provided).
