Complete Entities Files

Please, if you detect an error in my code, please tell me. Since my Eclipse is installing right now on my personal computer, if I made a mistake and didn't noticed, I will ruin the whole program. Thanks.

99.999% percent @PEMapModder 's code. I just modified it to fit with other Entitites and Entity IDs.

The one I had problems with is with the Falling Block entity, since I don't think it has an specific health, I may try later with 0 health.
