Title: fix bugs where it may fail to protect blocks

Updated isProtected method so it now checks if the sign attached or the rail above is protected.
Removed storage code for blocks below rails or attached by signs, since we don't need them anymore.
Removed how it used to unprotect nearby blocks when a block is being destroyed.
- the removed code used to unprotect anything include signs and rails, and we don't the code anymore since we are now checking the signs and rails themselves.
