Directory Filter Adjustments

[wrenaria]

This is a high priority issue to complete prior to launch. We need to make a few changes to filters to make behavior better align with user expectations when filtering the directory.

1: Remove keywords from the "Name or Keyword" freeform search. We will just search Name.

2: Add the rest of the directory tags to the Subject Area filter. This involves a few changes:

• Rename Subject Area to Expertise
• Use option groups to split directory tags into two groups. -- The current Subject Area tags should be listed first under the group heading Academic Subjects -- The rest of the tags will fall into a group called Other Expertise -- The hint text should read Select Expertise

Since we are losing the ability to search the "areas of expertise" free-form text, I would like to circle back and talk about splitting search out from filters for a more robust directory experience post-launch, but this will work well enough for now.
