[Frontend] channel heartbeat

[b-g]

• [x] missing y-axis start and end ticks; missing max y-axis value label
• [x] missing y-axis on the far right
• [x] wrong date format e.g. May 17, 2015 vs. much shorter ones in layouts
• [x] inconsistency of url and title: "channel heartbeat" and /heartbeat vs "channel land" and /channel-land –> rename to "channel-heartbeat"
• [x] date picker forgets selected dates
• [x] bottom footer should be sticky and always visible
• [x] missing "back" button, left of page title
• [x] links in menu are not working
• [x] missing select channel mechanism e.g. select via click in left list a channel
• [ ] hide or mark empty channels in the left list (as discussed by Alex & Benedikt)
• [ ] it would be nice if switching times were animated (curves update "hard" at the moment)
• [ ] y-scrolling on the entire page is rough and not very smooth (if too much effort: ingnore it)
• [ ] missing, jump to message mechanism (detail tooltip of data points of the curves)

What should happen if your click on the channel on the left? @b-g

links don't seem to be clickable inside the hint of react-vis

@OrKoN RE: What should happen if your click on the channel on the left? Channel is selected: curve become green, left list item gets yellow background

@b-g I thought this is on hover only

@OrKoN RE: links don't seem to be clickable inside the hint of react-vis that's a pitty, no way to get this clickable?

@b-g I tried again and unfortunately there is no way to make it clickable. I have created an issue in the react-vis repo. Maybe I will get help there.
