#6022: [with patch, needs review] latex.py: if dvipng fails, use dvips and
convert
instead

On systems where dvipng is installed: If in a %latex cell, dvipng fails to
produce a good picture, you get basically nothing. With this patch, this
failure is detected, and dvips and convert are then used instead. The
failure is detected by running dvipng with the '--picky' option; with this
turned on, if dvipng produces any warnings or errors, no png file is
produced. The code then sees if there is a png file; if not, it runs
dvips and convert.
This patch also fixes a long-standing complaint of William's: now when
there is a problem in a %latex cell, the .log file is printed
automatically, instead of just printing the message "An error occurred."
Apply on top of the patch at #6012.
