Tag input based on source

This would allow us to remove data from channels that don't exist or private channels, as well as spam/unwanted input from PMs.

I'm thinking of a relational design that does the following:

• Give a unique ID for each input method.
  • For example, a user on channel #lobby would have a different ID than the same user from channel #ubuntu.
• Have a table that contains the input method ID, its type (channel, PM, direct), and any references to a channel (in another table for statistics), a user (another table), or a direct input time.

This is currently done and inserted into the text database with a source id, which can point to an entry for a channel with a user id always present.
