Feature - track hit dice

[magroader]

A Pokemon has a number of hit dice, the type of which is probably dependent on species, and the pool is based on level (a level 5 bulbasaur has 5d6, a level 6 ivysaur has 6d8). A Pokemon's available hit dice can be spent from the pool at short rests. Half of them (rounded up, minimum 1) are restored to the pool at a long rest.

The Pokemon sheet should track the hit dice pool, and a long rest should restore half automatically.
