Tags: 2.0-1
* [3750b2cf] Merge commit 'upstream/2.0'
* [63637468] Removing Patch, not necessary anymore.
* [2fb580dc] Add new build-dependencies.
* [c57d953b] Run dh_autoreconf due to patches in configure.in
* [13febe39] Add patch to remove the libssl requirement.
* [5ae773fe] Replace libjpeg62-dev by libjpeg8-dev :)
* [1969d755] Don't build static libraries.
* [7cfe0a2e] Add a patch to fix the plugin directory path.
  As plugins are shared libraries, they need to go into /usr/lib,
  not into /usr/share.
  Thanks to Andrew McMillan
* [c1d0d9dd] Don't install .la files for all plugins and libraries.
