PsiDice

This is a relatively simple dice roller, modified to simplify the calculation of stun/kill points in "Champions" but perfectly useful if you don't require this addition.  It also utilises basic encryption to allow players in a PBEM game to make their own dice rolls, but send the result to the GM with an embedded validation code.

(The validation lacks a few key features which I will rectify some day when I'm really bored; don't trust it utterly for now)
