v0.3-alpha

Added:

• An option to increase the chance that destroyed blocks are dropped as items
• An option to disable damage to players
• An option to disable TNT and TNT minecarts
• An explosion size multiplier (originally @coolsquid 's idea)

Changes:

• Reorganized config options into categories. I suggest deleting the config file and letting it make a new one
• preventChainExplosion will now also affect TNT minecarts
• Minor internal changes
