Make histogram y-axis formatting aware of the tick size when formatting

kbn.byteFormat & kbn.shortFormat take an extra min_resolution param that indicates what size should be still be distinguishable despite the formating. For example if `min_resolution=100` and we fromat 1100 with `decimals=0`, the output will still be 1.1K . This is used in y_axis formatting to make sure the legends are able to correctly display a change of the current tick size.
Check if time_series bucket already exists, if it does, add to it. Closes #816
Histrograms should use the count search type when they only rely on facets.
Always show the refresh button

If one sets auto reload to 10m, it may still be handy to be able to refresh. Especially so because reloading the page would loose the current dashboard if not saved.

refresh was called twice with every timer expiry

Also unpacked  dashboard.set_interval to simplify logic a bit.

Note: set_interval used to call refresh() when called. This is un-expected when setting a long refresh interval.
