[cgiapp] slight documentation change

[Gabor Szabo]

Would it be possible to change the the documentation so the order of
the methods one can implement in
the subclass is the same in the documentation as in the order of calling?

Would it be possible to add the hierarchy to the documentation
something like this:

=over 4

=item new

=over 4

=item cgiapp_init()

=item setup()

=back

=item run

=over 4

=item cgiapp_prerun()

=item User implemented run mode

=item cgiapp_postrun()

=item teardown()

=back

=back
