* Check tweetbacks (search) converted to API 1.1 (optional). You need to
choose an OAuth acc handling the search.
* Already implemented OAuth function will call API 1.1 instead of API
1.0 now.
* Announce article: check for real URL lenght, as twitter makes it
longer sometimes.
* Tweeter: Count chars directly after a short URL was added. Counts URLs
as twitter URL length always.
* Article announcement with "uncompressed" urls did not work very well.
