implement account/pause and account/unpause endpoints. #10
Description
This should simply deactivate the account by setting the state variable accordingly 2 (profile created but account turned off temporarily by user) or to unpause, back to 1 (profile created, account active). Should also modify the other endpoints to make sure that they are checking the state of the account before executing their functions. For example, you shouldn't be able to hit the swipe endpoint if your account is deleted or turned off.
