Subject: Add automatic rendering tests

These tests render a HTML page in Dillo and save a screenshot which is
compared with another one rendered by a reference HTML file which
doesn't make use of the feature under test.

Running these tests require some additional dependencies to run a Xorg
server and capture screenshots of the browser, so they are only enabled
when configured with the --enable-html-tests option.

Additionally, running Dillo and opening local files requires a working
file dpi plugin. So, when running the HTML tests it is required that a
working dpid server can be launched by Dillo. To do so, Dillo can be
first installed to a prefix directory, the dpidrc file copied to
~/.dillo/ and then the DILLOBIN variable set to the path of the dillo
binary under test.
