Infinite Scroll: pass query arguments along with AJAX call in order to support a greater range of queries.

Instead of inferring the query that the IS client wants just from the AJAX
request URL, the query arguments for the initial page request are stored in the
client's IS settings and sent back to the server on each new IS request. This
allows support for search and archive pages, taxonomy and custom queries.
