1) fixed a bug where async tasks were not being shut down quite properly if server owners did a /reload (naughty don't do this).

2) fixed a NPE that would occur on paper servers, a warning will appear now until the issue is resolved on their end.

3) increased the default time for PreventProjectileExploit2 from 11 seconds to 22 seconds, and switched the protection to default to OFF rather than on.
(note existing configurations will not automatically change)
