Using dygraph to create interactive plots
Draw detailed plot on click

If user clicks on an plot, we create an overlay on which we draw a more detailed
plot with the last 720 data points. We are using dygraphs for this drawing.

This is a first version. In the future we can replace D3.js entirely by dygraphs.
Get at most last 1440 data points
Use custom interactionModel for anomaly

This interaction model is the default for range selector, as found in file
dygraph-interaction-model.js, plus a line to ensure we are not panning in the
vertical direction.
Change title font-size
Put style were it belongs
Put javascript were it belongs
New charts using dygraphs

We removed all D3.js from the chart, using dygraphs as our charting library.
We did so because it allows easier interactibe charts creation, implemented
as an overlay that appears as we click on one chart.

Also, we put Javascript code on monitor.js file and all styles on styles.css.
This should keep the code base cleaner.

TO-DO: Update charts dynamically.
Dynamic update plots
Don't need to show likelihood separate
Put back detailed plot drawCallback.
Show last 60 results on summary screen
Removing unused D3.js library
Remove D3.js import.
Added limit_detailed URL parameter

We can now specify how many past points we should fetch to display in the detailed
view. The default is 1440.
Cleaning-up more js files.
Using newer Jquery version.
Removed references to D3.js.

We've also added references to dygraphs and updated the screenshots session.
It remains to put the correct images in the docs/images/ folder, though.
Updated images, with new detailed one.
