added a tooltip settings section to the histogram settings editor. Currently the only setting defines which value is displayed on stacked charts.

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

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

Closes #426

Jshint and white space cleanse 

Fixing silly conflict

white-space cleanse, and added forin flags to a couple files that need to be looked at at a later date.

Setup a shared JSHint config file

Moved JSHint config into the standard .jshintrc file, so that it can be shared with the command line version as well as version that run within IDEs

Restored the "required_times" functionality

Bringing the rest of spencers changes in

Revert "added check for 404 response from the index_save call, assumes that auto_create_index is disabled and attempts to create the index before saving a second time"

This reverts commit 556925f8.

Restored the "fill all the holes" strategy to the ZeroFill class, and introduced the fill_style option ("minimal" and
"all" are possible values). Also allowed a set of required times to be specified when asking the times series for it's
data. This way, we can ensure in the stacked bar chart that each data point in use has a value preventing the bars
from stacking incorrectly.

added check for 404 response from the index_save call, assumes that auto_create_index is disabled and attempts to create the index before saving a second time
