first step to implement the WAeUP_Themes
it works like this:
there are theme-directories under waeup_design
WAeUP_Student and WAeUP_Backoffice. All theme-dependent stylesheets go there.
for each theme-dependent portlet there is a macro in theme.pt in the themes
directory.
The main_template.pt is in waeup_design and calls the macros from the themes
directory.
The student-theme looks quite similar to the original, but the
backoffice-theme is not usable.
For the "slips" there is a slip_template. To display the slips correctly all
slip-pts have to be modified to uses this template.
