Add random number generation to simulate dice rolls

[lhannest]

For example, I'm looking at the page for young brass dragons: https://open5e.com/monsters/young-brass-dragon

It would be nice if any text that describes dice rolls would be a hyperlink (bold and red would look nice) that when clicked perform and display the roll by generating a random number.

For example, the STR 19 +4 when clicked would generate a random 1d20 + 4.
The Perception +6 would generate a random 1d20 + 6.
The +7 to hit when clicked would generate a random 1d20 + 7.
The 2d6 + 4 when clicked would generate a random 2d6 + 4.

Probably you could automatically create a random number generating link for any any regex match of \d+d\d+( \+ \d)?.

I have some time this week, i'll take a look at getting this implemented!
