New bulk membership management and invite functions

As there are now some very large projects with many hundreds of members we’ve added the ability for project admins to search for members by name, email, or role, and optionally modify their roles in bulk. If you are a project administrator this is available under the Members’ tab in the project.

We plan to remove the “Invite Backyard Trappers” option as this is now redundant and a little confusing (the “Invite Members” function takes care of adding members to a project and sending links for both the simplified Backyard interface and Trap.NZ site). If anyone has queries or concerns about this please let us know.
