Advanced dice rolling

[rconnorlawson]

Currently, the dice command prints out the sum of all dice rolled. It would be convenient to show the value of each die:

> dice 2 6
3 1
Total: 4

Or possibly a distribution for larger rolls:

> dice 20 6
1 | ##                  | 2
2 | ##                  | 2
3 | #####               | 5
4 | ###                 | 3 
5 | #####               | 5
6 | ###                 | 3
Total: 78

Also, suggesting dice groupings on the command line, as if for mob's attach rolls:

> dice 4*(1d20 2d6)
 9  6 6
12  5 4
 5  5 3
10  2 6

There could be a whole syntax for this. For example, if you wanted to sum the 2d6 instead of showing them individually, something like this might work:

> dice 4*(1d20 2d6+)

Cool project!
