Templates 2

Enable ambient-occlusion (and "smooth lighting") on all Templates except for the slopes, which are still buggy with it

• new Template: Vertical Slab
• new Template: Tiny Slope
• Significantly reduce size of Template block entity NBT tags
  • Blocks will be automatically upgraded when loaded, creative ctrl-picked templates from before this update will not, and may act funny
  • "BlockState" -> "s", like 5 separate boolean flags -> a single bitfield "b"
• Reduce memory footprint of Template block entities
• Respect doTileDrops
• Improve creative ctrl-pick behavior on glowing Templates
• Adding a Barrier block to a Template makes it invisible (does NOT make it unbreakable btw)

Add more block tags, and add item tags

• Add doors and iron doors
• cool rivulet

• Add an Iron Trapdoor template
• Fix mod metadata and add more metadata

Thanks Patbox for noticing/suggesting

First public version. (2.0.0 was yanked for a duplication glitch.)
