Supporting for multi-configuration projects

Added new option in configuration for view. It is 'Show jobs for multi-configuration projects'. If you check it, you will see all of your jobs in your multi-configuration projects.
I have two jobs MultiConfigurationProject and Simple job, and first projects has 3 configuration with values: Windows, Linux and MacOS. And you can see, how it shows with ordering by Name.
