The SshCommand base class extends BaseCommand and provides the common pattern of calling startThread with a CommandRunnable that parses argments and then invokes the real logic. The new annotation @RequiresCapability can be declared on any concrete implementation of SshCommand to name a capability the caller must have before they can run the contained command. This is enforced inside of the DispatchCommand, which is what handles creating and delegating to any paticular command implementation. @AdminCommand is replaced by the new @RequriesCapability annotation, which is more explicitly declaring the administrate server dependency. Most existing commands have been ported to this SshCommand base class, cleaning up a lot of the code. A few special cases still exist such as StreamEvents or ScpCommand that are not trivial to port, as their start implementation is well outside of the common pattern. Plugin authors should be encouraged to extend from SshCommand for the foreseeable future. I eventually would like to get away from needing to extend this class, and instead use a simpler interface declaration, but that is a much bigger change to make with how DispatchCommand and BaseCommand are connected together.
