+Returns a hashref of parameters stemming from the current request's params,
+plus the ones supplied. Keys for which no current param exists will be
+added, keys with undefined values will be removed and keys with existing
+params will be replaced. Note that you can supply a true value as the final
+argument to change behavior with regards to existing parameters, appending
+values rather than replacing them.
+
+A quick example:
+
+ # URI query params foo=1
+ my $hashref = $req->mangle_params({ foo => 2 });
+ # Result is query params of foo=2
+
+versus append mode:
+
+ # URI query params foo=1
