Changed string lengths used in ALE documentation

- We had been using explicit lengths for fixed strings (", parameter")
  which was unnecessary and had to be updated whenever the string was
  changed. Switched to "character(len=*), parameter :: " for flexibility.
- Updates MOM_parameter_doc.* following commit 12c5838.
