dynamic.conf: Move the dynamic_1501 format definition (Redmine)

It had been added after the comment for the

dynamic_flat_sse_formats.conf: adjust algorithm names

Looks like there have been some copy&paste errors.
Make sure the algorithm names of dynamic_2000 - dynamic_2014 match
the algorithm names of dynamic_0 - dynamic_14.
E.g., use "md5($p.$s) (joomla)" instead of "md5($p)" for dynamic_2001.

Also, adjust the new password length (e.g., "PW > 55 bytes",
to match the max. password length of the corresponding
dynamic_0 - dynamic_14 format.
