*
* Commands for performing specialty dice rolling.
*
* !blindroll roll
* Players may issue this command to have a roll of the dice generated in
* secret to the GM only. This is useful when the player should not know
* the result of the roll (e.g., a Stealth check).
*
* Example:
* !blindroll 1d20+7 Stealth check
* This example would be rolled as a GM roll so that the results are only
* visible to the GM.
*
* !rigroll <num dice>d<num sides>:<modifier>:<actual rolls (comma-separated)>
* Occasionally, a GM may want to exert control over fate and have the dice
* fall a certain way (for cinematic reasons or to avoid a TPK). This command
* allows a GM to roll "in the open" and still get the desired outcome.
* This command cannot currently deal with complex roll types that are
* available generally in Roll20.
* Whenever this command is issued, the GM also receives a whisper informing
* him of the rigged roll. This is favored over simply denying players the
* ability to rig rolls because there may be times when the GM and a player
* conspire together for story purposes and require a particular outcome.
*
* Examples:
* !rigroll 1d20:+3:18
* !rigroll 5d4:+8:2,3,1,3,4
* The first example would produce a result of 21 (showing that an 18 was
* rolled). The second example would also produce a result of 21 (showing
* that a 2, 3, 1, 3, and 4 were rolled.
