normalize_to_source should strip out query-string params

[Brad Gessler]

Rails will sometimes feed a query param into the image_path helper (for example, image_path('pic.gif', :mouseover => 'foo.gif'), which causes an error in asset fingerprint. The following patch fixes the problem:

     def self.normalize_to_source(source_or_absolute_path)
+      # Rails will sometimes feed a query string through here and screw up paths
+      source_or_absolute_path = source_or_absolute_path.split('?').first
       if absolute_path?(source_or_absolute_path)
         source = to_relative(source_or_absolute_path)
       else
