/**
 * applyjss()
 **
 * currently only changes the behaviour of text entry fields in forms such that the first time they gain focus, they're cleared. This is
 * so that a field's value can be a descriptive text, but not be submitted every time somebody forgets to actually enter the real data in
 * the field.
 * fields with class "url" are initialised to 'http://' to help users not to mess stuff up.
