Finalizing #975 (Make timestamps link to timeline)

[Christian Boos]

Hello,

This is about an old ticket of mine. After some feedback from cmlenz,
I've removed the whole time window concept, and implemented instead a
more conventional link to the given day. The only difference from a
normal timeline view is that some events can get highlighted, see (1).

I think it's quite ready to go in trunk, but feel free to review the
changes (2) so that I can integrate feedback in the
sandbox/timeline-link-resolvers-tmp branch if needed.
