[High] Feature request: Message formatting redux

[BrotherSharper]

Related to #4 In order to show who did the roll please format the message as following:

Player name:
Command output

BCDice (Game System Name):
Command Result

The purpose is twofold, show who did the roll, and distinguish between a command that would have the same name but different output depending on the selected system.

I believe this is in line with what was requested. Please close this issue if the formatting is fine or add additional details on how to update it.

Thank you! Could the Player part and the BC dice part be split into two message cards? Possibly with the player one being created as a chat message from that player, so that modules that alter chat card color based on the player can change it and make it distinguishable
