Illegal blocks can be placed on pistons.

Expected behavior

The following blocks are illegal and can't be placed on pistons:

• Ladder
• Buttons
• Lever

Actual behavior

All the above mentioned blocks can be placed on pistons on any face. Buttons and levers will only be added client-side and will not be rendered for other players on the same server. The client can't interact with them, but I could observe some minor glitches possible with these, like client-side block duplication.

Steps to reproduce the behavior

Place one of these blocks on a piston.

I'm currently working on the ladder glitch.
