Updating user event coordinator view

Changing the Event Coordinator profile view so that an Event Coordinator
can see all of their events in a collapsible (accordian-style) object
that allows them to add and edit the attributes of the event or delete
the event. This corresponds to user story #6
Updating competitor and template models

Configuring the model with a scoped "for_event" lambda function so that
the comptetiors and score template will be viewable within the event
show page. This functionality allows for a particular event page to show
the competitors and score template for just that event. This commit
corresponds to user stories 8 and 10.
Refactoring views to showcase new functionality

Updating the view pages according to the previous commits that allowed
for competitors, templates, and judges to all be shown for a specific
event. This commit allows for the events "show" page to render specific
partials that show all of that events competitors, judges, and score
templates. More functionality to come within each of these collapsible
objects. This commit corresponds to user stories 6, 7, 8, 10, 27, 28,
and 29.
