DoH - Dice 0.2

Thanks to everyone's feedback, I've been hard at work implementing some new changes and systems to make the game more interesting (if not, perhaps, a tad more complex). Let's see what changed here:

- Vocation Passives: A hero's vocation gives them bonuses when they use dice that match their vocation.
- Hero Skills: Heroes have unique skills that can be used at the beginning of a turn to aid the party or hinder the opposition.
- Party Management: A simple screen to help you mix party compositions, also tells you how many of each dice your party has.
- Overflow Damage Screen: Now shows each overflow damage dice as it is rolled, for maximum climax!
- Hero Panels:  Have been redesigned to help understand at a glance (hopefully) all of your Heroes' stats.
- New Enemies: The Wyrd Shade now has a nifty ability that will give you some frights, and a boss battle now exists for when you unlock the last Hero. Speaking of which...
- New Heroes: As you win fights, you'll unlock new heroes. There are three to unlock, plus the 4 base heroes, for a grand total of 7 heroes!
- Better Tooltips: Albeit verbose, they should tell you exactly what to expect when using dice on which target.

As always, feedback is greatly appreciated. For now, I'm going to start envisioning how to make a proper exploration system to couple with this wacky dice combat.

Hope you all enjoy!
