Add Ability for Standby to Choose Patient

[ghost]

In order to add a patient's e-mail to state, do the following:

1. Add action types for adding a patient;
2. Add an e-mail parameter to the patient-reducer;
3. Add actions that will add a (default in this case) email to the store.

Then, add a view that requests the patient's e-mail from the standby user after she signs in.
