Remove image downloading

The special casing of Wordpress and image downloading was not reliable
for me so I have removed it, and tried to simplify the code in the
process. If you still need this functionality you will want to pin v0.2.1.

-## Special Handling for Different Feed Generators
-
-*feediverse* has support for some special cases of some feed
-generators. For example detecting the entries perma-link. Currently
-only Wordpress is handled, but others may follow.
-
-If a feed does not provide a proper *generator* entry, you can set it
-by adding a `generator:` value to the feed's configuration. See the
-seconds one in the example above.
-
-You can check whether feed provides a *generator* entry like this:
-
-    feediverse --verbose --dry-run feedverse-test.rc | grep generator

-## Why?
-
-I created *feediverse* because I wanted to send my Pinboard bookmarks to
-Mastodon.  I've got an IFTTT recipe that does this for Twitter, but IFTTT
-doesn't appear to work with Mastodon yet. That being said *feediverse* should
-work with any RSS or Atom feed (thanks to [feedparser]).
-
-## Warning!
-
-Please use responsibly. Don't fill up Mastodon with tons of junk just because
-you can. That kind of toxic behavior is why a lot of people are trying to
-establish other forms of social media like Mastodon.
