HTML: Use jqplot to draw profile.

Use jqplot to draw dive profile, Depth and pressure curves. add the
library Javascript files under the theme directory and editing the
exporter. Load them to the HTML template dynamically with
synchronization as they are dependant on each other.
Also Adding min version of JQuery that is needed by the library.
