Add frontend support for viewing an Event's Frames

Each Event has a 'Frames' button.  Clicking this changes
$scope.stream to false, hides the eventStream div, shows the
eventFrames div, and changes the text of the button to 'Stream'.

Each Frame is laid out in a box, with its associated image file
and details (delta, score, type, time).

The 'src' for each Frame's image was the difficult part.  The 'zpad'
filter is called for each Frame, so that we know how many 0's to pad
the Frame.FrameId with.

Finally if Frame.Type == Alarm, the box for that div is colored red.
