Tags: 3.6-rzb2752+dfsg-1
* New upsteam snapshot.  Contains important bug fixes to the installer.
* Correct typo in ampache-common.postrm.
* Remove courtousy copy of php-getid3, during repack.  Closes: #701526
* Update package to use dh_linktree to make the needed sym links to the
  needed system libs that were removed during repack.
* Update debian/rules to reflect upstreams removing/moving of modules.
* Update debian/ampache-common.install to reflect upstreams removal of files.
* Updated to use new apache2.4 API. Closes: #669756
* Updated /debian/po/de.po thx David Prévot for the patch.  Closes:  #691963
* M3U import is now ordered, fixed upstream.  Closes: #684984
* Text input area has been resized so IPv6 addresses will now fit, fixed
  upstream.  Closes:  #716230
* Added ampache-common.preinst to make sure that the courtousy copies of code
  dirs are empty so dh_linktree can do it's magic on upgrades.
