Suggestion #14826

Add more cell permissions and flags, similar to one's seen in survival.

Like survival, add more flags and subcommands to /cell

These would include,
- /cell containertrust
- /cell permissiontrust
- /cell fly
- /cell inspect ( to see who broke/accessed a chest, similar to claim inspect )
- /cell NoEnterPlayers ( useful for teambases, where players can set up private gear warps for their teammates)

These are the important ones I can think of which can be useful to have in prison.
