20 Apr 2015 - Bugfix, Translation Updates And Default Language Selection

Fixed issue #149 database migration was failing from old versions. Also:

• updated german translation
• added default language selection to the Settings >> Global menu. If no ?locale URL parameter is set then this language will be selected by default. Previously this could be also changed by setting up special value in <meta> tag (see this issue for more info). Now it’s set up in special cookie.
