Experimental! FINALLY Lava, Water, Sand and Gravel are allowed in twostate doors.

     To use, enable SpecialBlocks setting in config.
Grass no longer spreads inside a twostate door
Vines wont spread
Growing plants wont grow inside a twostate door
Fire can be place in a twostate door.
     It will not consume or spread and will self extinguish if not placed on top of a fuel source
     IE: netherrack, logs, etc. This is limited by bukkit api (there's no extinguish event) but here none the less.
Ice wont melt
Saplings wont grow into trees
Some block types are not tracked on placement but can be saved to a door with /dsave command.
     IE planting seeds, cocoa beans, bonemeal to grow grass, etc.
Blocks that pop during door creation are removed from twostate door record after door creation. Dupe Prevention.

Lava, Water, Sand and Gravel are experimental. They are linked in with the special block mode. I've tested it pretty extensively but there may be something I missed. Play around with it if you like. Post a ticket if you find something wrong.
