[DanbooruBridge] Fix bridge

Browse source 
This commit fixes an issue caused by self closing tags not supported
by simplehtmldom (<source>).

Adds a monkey patch to extend simplehtmldom with the ability to detect
that particular tag. Most of the code added is copied directly from
simplehtmldom (see vendor/simplehtmldom) with adjustments to account
for RSS-Bridge formatting.

Related to: https://sourceforge.net/p/simplehtmldom/bugs/83/

Notice: The tag itself is valid according to Mozilla:

The HTML <picture> element serves as a container for zero or more
<source> elements and one <img> element to provide versions of an
image for different display device scenarios. The browser will
consider each of the child <source> elements and select one
corresponding to the best match found; if no matches are found
among the <source> elements, the file specified by the <img>
element's src attribute is selected. The selected image is then
presented in the space occupied by the <img> element.
