Masquerade Support

The webserver_auth module overwrites the user variable if $user->uid doesn't match what is in the authmap table. This throws off the masquerade module when it tries to set the $user variable to someone with a different uid. (Its module weight is -10, so it always does this before webserver_auth.)

The attached is a small patch to allow masquerade to work alongside webserver_auth. Is there any chance of adding this support to the module?
