Update to 1.3.3

* Change tarball to released one

Changelog:
Version 1.3.3 (2016-10-01):
  - Support longer tweets in a few more places
  - Properly escape ampersand characters in user mentions to fix
    GtkLabel warnings about wrong escape characters in tooltips
  - Fix tweet length calculations for whitespace-only tweets
  - Check for duplicated entries in media arrays. This is apparently a
    problem on Twitter's side but led to crashes in Corebird (see #627)
  - Use the correct nsfw status of a tweet, i.e. the one that can
    actually show images.
  - Fix a crash when sending a tweet with multiple images attached
  - Fix tweet length calculation of quote tweets. This previously led to
    tweets getting rejected by the server even though Corebird claimed
    they were fine. See #628

Version 1.3.2 (2016-09-25):
 - Cope with the tweet length changes introduced by Twitter
 - Fix a problem with malformed media URLs
