Order members table and extend page length

[reginafcompton]

This PR updates the members directory table:

• orders the members by last name
• increase page length of the members table

http://127.0.0.1:8000/people/

These adjustments come from a request from an AHS board member.

@ecedmondson - there's not much to review here; usually I would not request a review for this, but I feel like we need some AHS WEBSITE COLLABORATIVE ENERGY.
