Configurable results display style depending on search criteria

First off, great module! I'm working on a project for a client and we needed an easy way to control the search results based on Content-type. Using Views was a good start, but didn't allow enough granularity for defining different views based on the content type selected (in the Guided Search).

I've attached a patch file in hopes that this can be committed to a future version of the code. I realize that the approach I had to use is not as elegant as if I had the content-type value to work with directly (and so had to resort to some substr hacks to get that info), but I hope my code gets us in the right direction to offering a more flexible integration with Views.

For anyone wishing to apply this patch, you should note the following:

1.) You will need to define a "generic view" which will handle all search results (if no content-type or a non-matching content-type is selected).

2.) Make sure you select that "generic view" in Administer > Site configuration > Faceted search > (Environment) > Results page > Display style dropdown.

3.) Next, you can create your custom views appropriate to the particular content-type by creating a new view (make sure you include the Environment ID as instructed in the module's documentation). Name the new view 'faceted_search_results_content-type' where 'content-type' is the name of your content type you wish to customize. (e.g. if you want to override the 'blog' results, create your view called 'faceted_search_results_blog')

4.) That's it! Go run a search by keyword, and using the guided to either filter your results, or start with guided and filter down. This works in any manner of search, with multiple/single word strings, using guided either before or after the search.

Please share your input (and David I'd appreciate your input on cleaning up those substr lines - I realize there should be a better approach).

Thank you again,
