Removed extra ">" in tooltip

Switched settings panels to use tip directive

Tooltip series identifier

added tip directive for defining question mark tooltips

Tooltip stacked values separation option

Duplicate alerts should not stack up

Allow users to delete the last unpinned query as long as there are pinned queries

queries, rather than just checking for other unpinned queries.

Added clickable urls to table row details view

when the query is not aliased.

kbn.query_color_dot() shouldn't use border-radius

Zero filled ts

Zero-filling will now happen any time there is more than one query being plotted, even if that there is only one data point
in the series.

moved the adition of the start and end time of the series after the reduce function checks each data point from elastic search. This whould resolve #422

switched out the border-radius powered query_color_dot's with font-awesome icons to maintain IE compatibility

The tooltip should be more responsive

centralized the tooltip creation and placement logic, and configured it to move out of the way when it would otherwise render off screen

Fixes filtering on array values from the micro-analysis pop-out

adjusted the shared kbn.top_field_values() function to preserve field values, specifically so that arrays are not flattened to strings

Closes #173
