Split donor creation form into two step process (See #47) T:9h00

Added Add Donor Section to 'Find Donors' tab, to work with the
following workflow:

- Before adding new donor, search for donor to see if they exist in
current system.
- If they do not exist, enter in donor info in short 'Add Donor' form
on 'Find Donors' tab that consists of all mandatory fields, as well as
Notes field.
- Once donor has been created, option to update donor details or
continue and update at a later stage.
