Allow to monitor build result and buildinfo

[schaefi]

Description

I think it would be nice if there could be a tab showing me the current build status and the build info data from an open obs project. I fetch this information all the time and a build or buildinfo can be broken even without the author having done any change. A periodic check of that data and maybe a button (do-it-now) would be very handy when working with obs image build projects.

Thanks
