Projects page: Allow multiple filters to be “active” at one time(eg ‘tech’, ‘stages’, ‘events’, ‘topics’). Show those filters on the screen to the user.

The projects page currently can only be viewed by one tag, stage, etc at a time. A member may, though, be looking for a combination of tags, or may be interested in more than one stage.

For example: "I want to find javascript projects that are not drifting or hibernating."
