Ability to filter on attributes instead of searching for them

### Current Behavior

It is not possible to filter out projects based on the Version attribute.
For example, I have many projects on my dashboard that have a version called **latest**. But the filter results are empty when typing in **latest** in the search box.

### Proposed Behavior

1. When typing latest in the filter box, only the projects with the version latest are shown.
2. Have a more comprehensive UI for filtering other than typing any attribute in the search box.

Start at the dashboard's project filter box and trace how its current text search handles the Version attribute. Verify that entering "latest" shows matching projects, then clarify the scope and expected behavior for the broader attribute-filtering UI before implementation.
