Rewrite CSLReferences environment...

...to avoid depending on enumitem, which plays badly with
beamer.  Instead we use a regular list environment.
Thanks to @jpcirrus for the concept.

We also restore the pre-3.1.7 format of the CSLReferences
environment, which again has two parameters. The first
determines whether a hanging indent is used (1 = yes, 0 = no),
and the second is the entry line spacing (0 = none).

Closes #9053.
