This goes together with my pull request to pandoc...
LaTeX template:  Use black for internal links.

This ensures that the table of contents will not be colored.

Also added commented-out code to use footnotes for internal
links (for print purposes).
LaTeX: added linkcolor variable
Added links-as-notes variable to print links as footnotes
LaTeX: Make TOC links black.
LaTeX: Use fontenc [T1] and lmodern fonts.

This gives better behavior for accented characters.
Use iftex instead of ifluatex, ifxetex. Simplified template.
LaTeX: Use blank \date{} if no date specified.

This way we don't get a date unless a date is explicitly specified.
Removed extra blank line.
LaTeX template: use ifxetex, ifluatex instead of iftex.

iftex is not in debian.
LaTeX template:  Separate `urlcolor` and `linkcolor` variables.
Resize pictures that are wider than \linewidth solution from: http://tex.stackexchange.com/a/6077
Fixed titleblock in markdown, plain templates.

Now it is just a single string. Previously separate
title, author, and date variables were used, but this didn't
allow different kinds of title blocks.
Beamer template: In section pages, don't print "Section" and number.

Similarly for parts and subsections.
Reason:  this is not properly internationalized, and for consistency
with other slide formats.

Closes #566.
