[PATCH] MemCached PHP client fix+feature

[Shiar]

First off, thanks for memcached.  We're now using it for storing login
sessions on our site cu2.nl (200000 visitors a day), and it's doing a great
job.

I hope this is also the right list for sending patches for the PHP client by
Ryan Gilfether (1.0.10).  It contains two small things:

- Fixed get() so that arrayrefs are handled correctly.

- Added no_rehash option and set_norehash(), as found in the Perl API.
