Beamer template: Consistent styles for figure and table captions
LaTeX template:  Allow bibliography to be used in place of biblio-files.

Closes #43.  Thanks to nougad.
Revert "LaTeX template:  Allow bibliography to be used in place of biblio-files."

This reverts commit 5f8d7968fe7c3d8da3363b7e3ff1a11914c081ae.

I'll use a different approach, setting the biblio-files variable
in the LaTeX writer. This will also work for beamer.

See #42.
