[Feature request] Add project enable/disable command

[Pieter12345]

Proposal:
Add a /javaloader enable/disable [project] command that sets the given or (optionally) all project disabled state(s). This disabled state would prevent JavaLoader and its users from loading or recompiling the project until it has been enabled again. This disabled state should be persistent through restarts, which could happen through a .disabled file in the project directory.

One idea would be to automatically enable the project on "load/recompile". At least that is how I would expect the command's behavior. Maybe with a short notice, that it has been enabled.
(If the same behavior applies to unload, an "enable" command is obsolete, not quite intuitive though.)
