Account for difference between boards when parsing XML

Apparently there's nothing similar among these boards: Gelbooru and
Konachan use xml attributes, and Danbooru uses proper tags.

This is workarounded by adding a new parameter to parseDanbooruResult()
which takes into account the difference between the two calls.

Hopefully JSON isn't broken in Danbooru so I never have to use XML...
