Small Visual Tweak to Event View

I wanted to push up a tweak I made internally, I felt it was beneficial to throw the event description up top instead of a generic "Event" in the header space. 

This may not be desirable if most people use the info/description box for more than a "title".

The result looks like this (info from Fireeye/Shadowserver reports, public)

I also modified my event add/edit fields as such:

        echo $this->Form->input('info', array(
                                'label' => 'Event Description',
                                'div' => 'clear',
                                'type' => 'text',
                                'class' => 'form-control span6',
                                'placeholder' => 'Quick Event Description or Tracking Info'
                                ));

The goal was to ensure anything which may be sensitive in nature, or detailed was input as an attribute for better tracking/securitycontrols/search though I did not put a hard limit on chars for the input fields/db as I didn't want to upset existing or imported no conforming events.
