[Erome] Extracting tags

[powerfulsaber]

Posts on erome often have tags. It'd be useful to have the ability to extract them.

I think this broke downloading search results, like "https://www.erome.com/search?q=girls". It get an attribute error "NoneType object has no attribute 'index'".

It's probably because it's trying to extract tags on a search when only posts have them. It should only try to when it reaches one in a search, or when given a direct link to one.
