Upgrade the precise32 package to 10up-precise32-0.3.box

Provides update nginx, mysql and php5-fpm
* mysql 5.5.30
* php5-fpm 5.3.21
* nginx 1.2.6

The previous package, 10up-precise32-0.2, which was running php5-fpm 5.3.10 was experiencing segfaults when met with some curl HEAD requests from the host machine. It's a pain to dev websites when you can't do basic stuff like that
