Update rubocop

And use settings from sgx-jmp

Copy in account activation logic from sgx-jmp

This is largely duplicated code, but the whole web-activation path should go

instead of the hack previously produced.  Instead of an account activation for 5
months, we insert 5 months of balance and then bill for only one month as is reasonable.
