Fixed Pick Block Results

We previously returned the Vanilla counterparts to our doors as the items to be used by the pick block button - used in Creative mode for replicating nearby blocks. This was incorrect because we would want to return the actual door item needed to place the particular door in question.

More importantly, this might solve our issues with WAILA reporting the wrong information when players look at our doors. I read the code for the most recent version of WAILA and it uses various functions to choose how to identify a block. The result of Block.idPicked() is probably used as the main source for the identities of our blocks.

After this PR went up, I also completed automatic versioning. Now we only have to update the version of DD in build.gradle and the change will be propagated to mod_pocketDim.java and mcmod.info.
