Pandas 0.19.1 has compatibility problems on Webfaction with Django.

In Panada the start of the 2 week resample interval in Pandas varied
with the time series being resampled.  Therefore, the matching in an XY
plot failed at times.  No problem with Semi-monthly averaging.

- Froze Plotly version to 1.21.1
- Added Day of Week to Hover text in Timeseries plot
- Added additional averaging periods to XY Plot and Excel Export
- Changed DropDown Label from "Gauge" to "Graph"

- Remove highcharts references
- Read sensor data directly from SqlLite to Pandas
- Make dashboard charts slightly smaller
- Improve handling of multiple y axes on timeseries charts
- Make pandas datetime indexes timezone naive to avoid a resampling bug

Also, cleaned up loading of JavaScript libraries.  Removed loading of
Highcharts library, since it is included in the Highstock library;
loading both caused errors.  The Highstock license was valid through Dec
13, 2015, so am loading the libraries current on that date.  Repaired
broken link to the Excel Export Highcharts add-in.  Repaired broken link
to the html5shiv Javascript library.

Locally referenced AHFC Logo.  Removed http or https from CDN references
so that site determines which transfer occurs.

Also kept Dashboard CSS file from being cached.

https sites will not load files from an http site, so needed to change
to https download of jquery and highcharts CDN files.

This reverts commit 7a524128.

Needed for sites that serve via https, as static files must come from a
https site.

Added a query parameter equal to the current time so a new file is
always requested.  Now, no need to rename the JS file every time a
change is made.  Lack of caching is not a problem, as page is rarely
reloaded and app JS files only take 200 ms or so to download.

Developer license for Highcharts was bought 5/8/13, version 3.0.1.
Minor releases for a year are allowed.  3.0.10 was released 4/22/2014,
so falls within the window.  No other minor releases occurred prior to
version 4.  For Highstock, license was bought 12/13/2014, version 2.0.4.
No minor releases have occurred since then.  Code right now will
automatically use minor releases, as it references
/stock/2/highstock.js.

Had to change JavaScript file names to ensure cached files are not used.
Also changed occupied shading color for Time Series graph.

Added the checkbox control necessary to turn On and Off the shading of
occupied periods on the Time Series graph.

Sensor List HTML was being escaped and not displaying properly when
loaded directly from the server (through clicking on the Map).

Also implemented a Test button for arbitrary testing.
