Added Support for Safari and mobile Safari.

• added fetch polyfill
• fixed viewport for mobile
• added overflow scroll for sidebar

Thanks!
I don't have an iDevice, so I can't test it for Safari, working for mobile Chrome.

Does the scroll-overflow help anything on Safari, doesn't make that much sense for Chrome.
Sidebar should be responsive and dismissable anyway.

Overflow scroll also helps in Desktop browser, when showing more sensors in sidebar. (zoomed out)

That would be overflow-y, not overflow-x though, if we want the vertical list to be scrollable.

[ubahnverleih]

ok, overflow-y would be the right one and i don't know why overflow-x has the same effect. And auto would be the better value

[ubahnverleih]

fixed in PR #12

overflow is a bit quirky, certain combinations for x/y are not possible: http://stackoverflow.com/questions/6421966/css-overflow-x-visible-and-overflow-y-hidden-causing-scrollbar-issue/6433475#6433475
