update_without_callbacks is defunkt

[dmathieu]

On rails edge, the update_without_callbacks method doesn't exists anymore.
It should be replaced by save(:callbacks => false)

I've done it on my fork : http://github.com/dmathieu/friendly_id/commit/4beb197b06852de2718b67dc4a641b52d10e50d4

Check for update_without_callbacks; compat w/AR 3.

Thanks a lot for this. I changed the implementation a bit because I need to preserve backwards compatibility with 2.3 and 2.2.
