Title: Update regex for youtube videos.

Video identifier can also include '-' and '_'.

Related to fedwiki/wiki-plugin-video#2, thanks to @michaelarthurcaulfield for identifying the deficiency in the plug-in.

This also raises a question, why is the drop code here rather than being included here from the plug-in?
