Re-added user messages to home page
Added visual cue to page search

This is to help remind the user that they might not be seeing
everything because of the in-page filter.
Fixed #10.  Added proper date-sorting to unavailability
Published 2014.12.07 changes
Fixed #11.
Fixed odd day-offset in resource view....
Fixed #2 and changed unavailability filter to CourseId

This will prevent somebody from messing up things by adding a funny
class #.
Completed #9.  Added color context to resource view

Not crazy about the colors right now, but the added data is certainly
informative, so we’ll leave it until somebody combos up with a better
color scheme.  Todo:  Add option to turn off this color code stuff at
it could be annoying for some.
