Bug 17282: Ability to create charts for SQL reports

Add a form under report's result that allow to configure and draw a
chart (pie, bar, line and combination).

Pie: Usefull only for a two-column report's result

bar: Horizontal: Can be horizontal or vertical (check/uncheck
horizontal checkbox),
     Group: allows to group columns (stacked bar chart),
     Line: show some columns as line in a bar chart (combination)

line: line chart :)

This patch adds 2 new js libraries: d3js and c3js:
  - c3.min.css
  - c3.min.js
  - d3.min.js

Test plan:
- Apply this patch,
- execute a report,
- click on show chart settings button (in the tool bar),
- draw chart (click on draw button),
- check the chart

Features:
- Include all rows (ignore pagination),
- Download the chart (svg),
- Choose x column and y columns,
- Exclude last line (Rollup)
