[FEATURE] Add possibility to catch exception during rendering

Currently exceptions throw when rendering single
content objects bubble up to the default exception
handler and break the complete frontend.

This change adds the possibility to register an exception handler
for a content object which can render an appropriate
message instead if wanted (e.g. in production context).
