User story #756
As a user I want to improve the UI of issues view
Issues list & form
- Render pending effort with "X hours" format.
- Render that label as a link to show a modal dialog with the history of pending efforts of the issue.
- Render pending effort just on tasks.
- Render position just in user stories.
- Remove not needed ID attribute in pending effort link.
