Story E002-002: Import security layer and set up roles to distinguish between planner/speaker/audience member/board member

User Spring Security Plugin

Roles:

-Admin
-Planner
-Speaker
-Audience Member
-Board Member

Acceptance Criteria:

-Audience members should be able to self-register
-Admins should be able to create users
-Admins should be able to assign the speaker role
-EventPlanners should be able to create users
-EventPlanners should be able to assign the speaker role for their events
-Users may have more than one role depending on an event. ie, for Event 1, User A may be a speaker, but in Event 2, is an Event Planner, and for Event 3, is an audience member

I'll take the first crack at this one.
