Merge branch 'behat-support'
improved to automatically update config.yml assetic section and App.Kernel.php with the active theme, each time the website is deployed.

- refactored the .active_theme file to store both frontend and backend themes
- refactored ActiveTheme object to handle the new .active_theme file. Backward compatibility is preserved, but this change introduces a BC because the getActiveTheme method has been replaced with the new getActiveThemeBackend one
- introduced a BC to DeplayerInterface because now it is required an instance of ActiveTheme instead of the Theme
- updated tests
