block states can't be used in /give, /clear and /replaceitem, but can be used in /setblock /fill /execute detect and /testforblock

As of 1.11 snapshots you can use block states in /setblock, /fill, /execute detect and /testforblock, rather then meta data, this makes /give, /clear and /replaceitem stupidly hard to use, to get the right item.
This also affects models; models are named acacia_log, where in game you have log2:0.

The best way to fix this is to make them separate blocks (like the model files), in the attachments (the_flattening.txt) is a LONG list of blocks that shouldn't be block states but their own block.
The model/block state files should be renamed too when they are not the same as listed below.

This list contains:

• Block states that shouldn't be block states.
• Logical changes.
• Changes that'll make the code more sane.

Build up like this:

• Current collection
  • What it should be (old data value(s)/old block state(s)/{old nbt data})
    • Additional note(s)
