Oh heck yes let's use metrics

some permissions tweaking, not sure if it will actually improve memory
usage at all.
reload tweak - let's not use a try/catch to check if perms is null.
on enable, there's no real need to instantiate variables if we're only
using the value once. Also, not calling perms.enable() could have been
disastrous with previous perms versions. Let's fix that now, after the
fact :D
