Add a custom value generator for automatic web tests for "ark" attribute

We will soon require that inserted "ark" attribute match a regexp
pattern. In test_saem_ref.py's automatic web tests, ark attribute values
are automatically generated and will most of the times not match this
regexp. So we need to implement a custom "value generator" for
"ark" attribute so that it matches expected regular expression.

(How does this work? Apparently, the metaclass of ValueGenerator make is
automagically used by AutomaticWebTest subclasses defined in the same
module.)
