JIRA Sprint dashboard

[thomas-gerber]

Description

A dashboard focused on giving users a good overview of what is happening in a chosen sprint.

Note that points in sprint and points done in sprint are not very precisely computed. At the moment:

• changes in points in sprint only support creation of issues AFTER the corresponding sprint has started; if an old issue is added during the sprint, its points are attributed at the beginning of the sprint
• points done in sprint only cover points for issues that were NOT moved out of the sprint AND completed during the sprint

Relates to #113.

Type of change

• New feature (non-breaking change which adds functionality)

Checklist

(Delete what does not apply)

• Have you checked to there aren't other open Pull Requests for the same update/change?
• Have you added an explanation of what your changes do and why you'd like us to include them?
• Have you successfully run tests with your changes locally?

@chalenge I decided to keep pie charts because:

• alternatives where uglier as far as I tested
• they have the long tail Other bucket
