Added Class Time File Scanner to doAddClass.php
Lots of styling adjustments

Made tables on manage pages pretty. Made input forms in adds pretty.
Other minor things

connection.  I'll test stuff out tomorrow. Maybe it worked, but I doubt
I got it on the first try.
Merge branch 'CourseScanner-Wiring'
