New version with character levelling, class abilities and more

Recreant now features player character levels with experience points added for all enemies that you encounter. Levelling the player character increases your health along with giving you the opportunity to select a bonus to your statistics every second level.

I've also added class abilities:

* Mercenaries have the veteran ability. This reduces the effect of weapon and armour weight on attack and move delay by 10% per character level. At higher levels, this becomes a huge bonus to heavy weapon and armour users.

* Gallants have an aura of valour which grants a +1 morale to all allies in sight for every two character levels.

* Confessors have an aura of fear which causes a -1 morale to all enemies in sight for every two character levels.

* Blackguards have the murderous trait. When a blackguard is in the dark and his target is in the light, they gain a +2 criticial hit chance for every character level.

Please let me know if you try the game out and you have any feedback.
