Add Notes to Race Events

[Von-Seth]

For Feature: #3

Story:

• As RC I want to be able to add notes to race events. Each course will have a written set of instructions that go with the mapped course, this set of instructions is visible to racers. The instructions could contain information other than just course details and could include PDF files.

  Acceptance Criteria:

• [ ] Within a mapped race there should be a section to add text notes and attach pdf files.
• [ ] Notes are visible to racers alongside the mapped course.

On Hold Reason:

• [ ] Story too much info, not a user story
