Custom auto-tagging (#303)

### Notes
This adds the ability to modify the auto-tagging function of Valkyrie
based off of a defined list of `PRIVATE_CHANNELS`. It also will match
the tagging to the role specified, in order to have custom roles tagged
for specific threads started in a channel.

### Handling IDs
Alternatively, we can also modify this to work directly with channel /
role IDs rather than names, but in testing it seems to be working as it
should.
