Login block doesn't work with URL Alter (patch included)

When using the URL Alter module along with the login block, Front Page does not allow the user to log in (it just displays a 404 error, and the user remains logged out.) The problem lies in the custom_url_rewrite_outbound function, which, because it is implemented in URL Alter, is not being properly invoked for Front Page (at least, that's my understanding.) The solution is to implement the hook_url_outbound_alter function. The included patch should take care of this. In the event that URL Alter is not installed, then it will implement custom_url_rewrite_outbound to call the hook_url_outbound_alter override. This seems to be working for me now...

This is my first attempt at creating a patch, so I hope it works...
