Updated some stuff

Found the net error, has to do with server/client stuff :/

Updated metadata code WAYYYY CLEANER

To register a block with metadata do:
registerBlockMetadata(projector, new HashMap<Integer,String>() {
{
put(0,"Beam Projector Block");
put(2,"Satelite Projector Block");
put(1,"Radial Projector Block");
}
});
The first number in the put is the damage, the string is the name,
projector is the block itself
