hgweb: infinite scroll support for gitweb style

hgweb: avoid invalid infinity scroll request when overwritten web.style Infinity scroll is broken when you override the web.style in the following ways: $ hg --config='web.style=gitweb' serve $ open http://localhost:8080/shortlog?style=paper ajaxScrollInit should use http://localhost:8080/shortlog/%next%?style=paper. however, http://localhost:8080/shortlog/%next% is used actually. It is missing style parameter. This patch add style parameter to request url.
