Fixed option for Block
Create an option for all blocks that does not allow non admin users to change any properties of it. The "fixed" block option removes the edit, remove, clone and move buttons from block, and remove the block's drag and drop behavior.
This option can only be seen by environment administrators. Once it is marked as true, only the environment administrators can see it's edit options and move it.
This feature can be very useful for templates creation and to define fixed blocks for all pages.
