logmanoriginal 6eadc6ca6f [TwitterBridge] Show quotes and pictures
This adds new features to show quotes and pictures in feeds.

Quotes will show up on top of a tweet and are separated from
the quoting feed by a horizontal line.

Pictures that are embedded in the tweet will be captured and
attached to the feed using enclosures. By default the picture
will also be shown in the feed itself. This can be disabled
using the option '&noimg=on'

Some codes are now split into separate functions so they can be used
for tweets and quotes alike.
