add setting to ignore query string when building page heatmaps.
Currently, the software assumes that the page's complete URL is one grouping--and I can see how that use case fits in.
There are other instances where the url parameters (after the '?') change with every page load which is problematic for generating the heatmap. Being able to ignore, or otherwise selectively whitelist certain parameters will go a long way to grouping the heatmap.
