[FEATURE] Render Error Pages via Fluid

A new class called "ErrorPageController" is introduced
which sets up a Fluid standalone view to render the
actual error page as a Fluid template, instead of the
old marker-based approach, as the end of the marker-based
templates is near.

The ErrorpageMessage and AbstractStandaloneMessage
classes are deprecated now.
