Added search input auto focus, updated README

The javascript controller has been updated to include a call to focus
the cursor on the search field. This previously had only been seen on
Firefox, and was assumed to be a weird FF-specific bug. Adding in a
timeout to allow elements to finish loading allows the field to be
focused as expected.

Also updated the README to include clarification for IP address
tracking.
