+ Start cell on new line unless it's a single Para or Plain.
+ For single Para or Plain, insert a space after the `|` to
avoid problems when the text begins with a character like
`-`.
Closes#2604, closes#2606.
Thus you can say `papersize: a4` and the latex will contain
`a4paper`.
This change may break some existing workflows; if you currently
specify `a4paper`, you'll get `a4paperpaper` which is meaningless.
However, the change seems worth it, as it will make the
`papersize` variable work uniformly across ConTeXt, LaTeX,
and html->pdf via wkhtmltopdf.

If `geometry` has no value, but `margin-left`, `margin-right`,
`margin-top`, and/or `-margin-bottom` are given, a default value
for `geometry` is created from these.
Note that these variables already affect PDF production via HTML5
with wkhtmltopdf.
Variables margin-top, margin-bottom, margin-left, margin-right.
Setting them with css inside @page doesn't seem to work, at least
with the released wkhtmltopdf.
* Added `thanks` variable
* Use `parskip.sty` when `indent` isn't set (fall
back to using `setlength` as before if `parskip.sty`
isn't available).
* Use `biblio-style` with biblatex.
* Added `biblatexoptions` variable.
* Added `section-titles` variable (defaults to true)
to enable/suppress section title pages in beamer
slide shows.
* Moved beamer themes after fonts, so that themes can
change fonts. (Previously the fonts set were being
clobbered by lmodern.sty.)
One could also tell users to add this to header-includes if `subtitle` is desired for `article` and so forth, but I will leave it out for now for the sake of simplicity:
```tex
\providecommand{\subtitle}[1]{%
\usepackage{titling}
\posttitle{%
\par\large#1\end{center}}
}
```
`file:filename` rather than `file://./filename`.
I think this is right; it matches what we had before
with people actually using the ICML writer, and seems
to match examples in the spec. I don't
have a copy of InDesign I can test on, though.
@DigitalPublishingToolkit and @mb21, can you have
a look?
