extendsed the network code to be able to work for entities as well as tiles. rewrote a lot of the ghost entity to ditch the dataWatchers and use the new networking. Added some handy things into the networking code such as getting the amount of ticks since a certain change to a property, so we don't have to have tick timers everywhere.
Created README

Need more information on the build process and licence.
I'll refine the whole document once I'm sure of the details.
Fixed README

Seems github has some markdown parsing issues.
