Feature Request: Named rolls

[DanielGeffers]

As a frequent pnp user I want to name rolls, so that the result is easier to read for others & later.

Possible input syntax: /random Is this a good bot?

Output: (d100) 99 Is this a good bot?

Context: We are using the Bot for Inspiration and NSC decisions in groups with many members. Thus it would be great to have this feature, and it should be easy to implement.
