Allowing saving HTML versions of likes, retweets, and bookmarks too

[micahflee]

I received a feature request to allow saving HTML versions of each like. And some people might want to also save their retweets and bookmarks too. I'm not sure how how many people actually want this feature and if it's worth adding new options to the user interface for it, but it would not be hard to implement.

This issue is for discussion to decide if we want to add it.
