Uc91v2

This PR contains UC 91, including the Main and Alternate flows. The main changes made in this branch are:

• The ability for the patient to provide their health information. This information is stored in the personalhealthinformation database table.
• Added additional unit tests for health information.
• Added additional selenium tests
• Fixed UI issues brought up in iteration 1
• Fixed code style issues from iteration 1

To run the tests, do the following:

1. First, run mvn install -DskipTests to build and deploy the website (this will ensure that the selenium tests work as expected)
2. Run mvn test -Dtest=AddPreRegisterPatientActionTest to run the unit tests
3. Run mvn test -Dtest=PreRegisterPatientTest to run the selenium tests
