steps to upgrade from 1.1 to 1.2

hi any steps in upgrading? it would be good if we add it in documentation

In your home directory ```php rm -rf cphalcon/ git clone cd cphalcon git checkout 1.2.0 cd ext ./install

/etc/init.d/php5-fpm restart ```


1.2 is now available on master:

git clone
cd cphalcon/build
sudo ./install


Great Thanks!
