library browse: add tab 'random album'

[sludgefeast]

Large music libraries have the problem, that albums get lost - you have forgotten that they even exists. And sometimes you don't know what to hear next. (at least my problems) Therefore I have added a tab that randomly shows an album.

Can somebody please look at the build error? What's the problem? A local build with my Crashlytics API key is successful. But a build with the project default API key leads to the same error message.

this test shouldn't even be run, so disregard it
