config: do not hardcode sharedir

Instead of using a static SHAREDIR at compile time, use a list of
standard paths to use at runtime for templates, config files and
stylesets.

This implies removing all default filters in the default configuration.
Replace them with basic commands. New users can configure the filters as
they wish.
