New Revision: 5976

Log:
Add a new PageRenderer class

This class can be used to set mpuls application specific
renderers. In addition to the get_rendered_page function
it is possible to pass additional arguments to the special
renderers. This has become necessary for mpuls_S and it's
university specific key values for studienfachrichtung.
It would have been possible to implement a special renderer
for the studienfachrichtung field with the get_rendered_page
function too but the new PageRenderer class is more flexible.

Part of mpuls/issue3156 (muls_S: Stipendienserver hochschulspezifische Schl?\195?\188ssel)
