Changes

Finalize the event's list view of the frontpage
This commit implements the EventManagedBean file with temporal data to
test the view. The index.xhtml file contains the creation of the view of
events using bootsfaces and implements the use of the temporal test
data. The style.css file contains the view styles and the necessary
fonts to represent the categories. So far the communication between the
managed bean and the event's ejb it's not implemented and it's still
left to do
