#7 CSS layout doesn't work in PHP 5

[John Pulles]

The layout of an existing page is not correct when
using PHP 5: all buttons are below each other, and the
map may appear in the left top corner.

In PHP 5 the __CLASS__ constant equals the class name, while
in PHP 4 it is lowercase only! The solution is to use
'strtolower(__CLASS__)' in the getCSSClasses() functions.
Note that the class names in the mappingwidgets.css file are
lowercase also.
