v78 - fixed modding, destructable crates, loot

Hi,

i updated to v78.

fine tuned some unit behaviour.

Adjusted HP of the player to make it more exciting, less spongy. Though added a drop chance for medipacks when killing a unit in melee and when destroying crates.

modding should now work perfectly.

Modify the pngs in the folder, press U to update the spritesheets in game with the ones in the folder (currently they match, so you know where to draw), try it around and let me know if you found made something cool. Happy to discuss a spin off etc.

Also added the option to destroy crates with melee. Crates have a chance of dropping loot / useful items.

Armor is in as a prototype, it only lasts for the round you find it in. Will be refined later.
