Fixed bug that caused the wrong list to be loaded when the return key was pressed in a search text field of a list.

fixed #681 - removed all onblur, checked onchange for function and removed it in filter panels. Added jquery keypress (event 13 -> enter) and tested it in different browsers

Missing div ending and clean up footer tabbing

Added a new theme called no_navimg. This template removes the icons from the top-Navigation if you don't like them
