call onInit on hot-reload, cleanup, remove warnings

onInit is now called on hot-reload, for the whole plugin. Arguably, this
is not expected behavior, since only one file is being reloaded, but
this is the easiest way to do it, and the entire hot-reload process is
only for development purposes. Open an issue if this breaks your stuff
:^)
