Add basic membership and roles.

Use the membership authentication and roles-based authorization built
into .NET.

Membership:
http://msdn.microsoft.com/en-us/library/tw292whz(v=vs.100).aspx
Roles: http://msdn.microsoft.com/en-us/library/9ab2fxh0(v=vs.100).aspx

Most of the changes have to do with the web.config, where membership
configuration takes place. Each role (nurse, pcp, physician, etc) has to
have their pages in a separate directory; the directory must contain a
web.config that authorizes users in that role to access. These
directories, along with the appropriate web.config and a sample aspx
page, were created.

Roles (and members) can be added and managed programatically, or by
going (in Visual Studio) to Website >ASP.NET Configuration and clicking
on the "Security" tab of the resulting page. Sample users were created
with the appropriate permissions. Each user's email is of the form
`samuelbritt+<username>@gmail.com`, and each user's password is
`organic!`. Each user has a security question and answer that are both
just its username. The users are listed below (the `admin` user has
access to all pages of the site).

- pcp1
- physician1
- nurse1
- stats1
- it_officer1
- admin

Many database tables were added in this commit to support user
membership and user roles; the database.mdf.sql script was updated to
reflect the new schema. The tables were added with via a tool. I do not
think it will be necessary to run this again, but for future reference,
the following command was run on the command line:

aspnet_regsql -A mr -C "Data Source=.\SQLEXPRESS;Integrated
Security=True;User Instance=True" -d
"C:\path\to\project\website\APP_DATA\DATABASE.mdf"
