Fix status in pipelines list and clean up styling

[kroeschl]

Justification

The status icon is broken in the pipelines list view at https://dev.azure.com/<org>/<project>/_build.

Implementation

• Look for href on .bolt-table-link, not parent .bolt-table-row.
• Use appendChild() to add status icon, not append().
• Use solid icons instead of non-solid with giant border.
• Use different colors for paused and disabled.
• Clean up CSS and match size to last build status icon.
• Update version and release notice.

This fixes #254.

Testing

Tested rendering on both the pipelines list and the single pipeline view:
