Load before worlds do.

When worlds first load, events start happening before plugins normally
(POSTWORLD) enable. This means that regions and other protections won't
be active when these events are called.

This shouldn't break anything that depends on us, e.g. custom flags,
since our API contract already states that should be done on load,
and all plugins are loaded on startup (just not enabled).
