Gloomhaven class: Human adept (v0.1.0 pre-alpha)

Here's my first draft of a Gloomhaven martial artist class, for posterity. 

Warning! Needs further playtesting, has no elemental affinities, and has no XP values. 

HP: average.

Lore: -

Expected problems:

- Low durability (few self-heal and shield/retaliate abilities)

- Low damage (few attack abilities)

- Positioning problems (push might be a mistake if this class is melee)

- Niche overlap with the Brute class (2nd edition is also melee and based around forced movement)

Rework predictions:

- Add a special mechanic (as in Frosthaven)

- Add more attacks (as opposed to the Brute)

- Rework mobility/forced movement
