Hashtag representation

[Gargron]

Hashtags go inside the tag property along with mentions, but don't have a special Link subtype.

Furthermore it's not clear what attributes such an object needs. In OStatus, hashtags are represented like <category term="example" /> - without hrefs, namespaces, URIs, just the term itself.
