creative block data placement options

There are some blocks that have uses in shading and details on surfaces, but are not able to be placed. Similarly, if you do place them with debug stick or others, it breaks or updates when another block is placed next to them. 

I propose two options in the creative menu or debug stick interactions, updateblock and placeblock. Selecting these makes every block get an additional flag. One for preventing block updates, one for bypassing placement restrictions. 
This is similar to axiom, but having a flag created and placed on the block itself assures that people without the option wont be able to accidentally update an area of bypassed blocks.
