Project links in dataset catalog should link to a filtered catalog by just project

[bryanrcarlson]

Currently, the dataset catalog shows a "path" where it's "{ZoneName} / {ProjectName}". The ZoneName links to a dataset catalog filtered by zone. The ProjectName links to a dataset catalog filtered by ZoneName AND ProjectName.

It would be more useful, and more intuitive, if the ProjectName links to a dataset catalog filtered ONLY by project.

To make this more intuitive, the formatting of the ZoneName and ProjectName as a "path" should be removed.
