D3, NVD3 and Angularjs versions are obsolete

[JF Taltavull]

Rally 3.4.0 uses the following versions of D3, NVD3 and AngularJS libs and css to build task reports:

D3: 3.4.13
NVD3: 1.1.15-beta
AngularJS: 1.3.3

and the last published versions are:

D3: 7.8.5
NVD3: 1.8.6
AngularJS: 1.8.2

I gave a try to "rally task report" with the above versions for NVD3 and AngularJS, and version 3.5.17 for D3. The generated report shows the following anomalies:

- Overview tab: the "distribution" donut is dark grey instead of blue and the chart on the right disappears
- Details tab: the pie slices loose their color (but the pie is bigger, so more readable...)

Changes have to be applied to the calling Javascript code to adapt it to the new versions of these components. According to the pretty good test result, these changes are likely to be light, hopefully.
