Renamed WListBaseAdapter -> WClassesBaseAdapter to better reflect.
Added in a "No Effect" message to the week picker dialog if "Display all classes" was turned on.
Moved the initial day and week setup to onResume so it will always default to the current day and weeek.
Fixed up a bug, where "Display all classes" would sometimes not work or the UI would get confused (due to missing return/break inside switch case).
Fixed up a related bug, where the views in the classes list were being recycled and the week visibility was not set to gone.
Added in the "Upcoming" fragment file (still needs to be activated).
