Removal function major upgrade

Renamed "delete" function to "remove". While the command does delete comments, the primary purpose of this command is to remove tokens that were given in bad faith.

Significantly improved remove function:
* - Checks for confirmation to determine if a token was awarded
* - Deletes (not removes) all comments left by bot if a confirmation was found
* - Reduces the flair count
* - Replies with a standardized removal message
* - Removes (spam=False) the bad comment so that it won't be caught by the bot again

Still need wiki (partially completed module) and scoreboard (no module) portions. These will be completed along with the modules in question. A placeholder has been added as a reminder.
