Updated link to Ubuntu script in the readme.
Merge pull request #7 from PatrickMa/master

The link to the Ubuntu script is outdated!
Put Homebrew location earlier in PATH. This is recommended by the "brew doctor" command and on a fresh machine, *not* doing this will result in an error when trying to create a Postgres database from a Rails app like:

could not connect to server: Permission denied (PGError) 
Is the server running locally and accepting
    connections on Unix domain socket "/var/pgsql_socket/.s.PGSQL.5432

However, Postgres will be running. This path change and sourcing of ~/.zshrc must be done *before* installing the "pg" gem.

going back to ruby 1.9.2 for the sake of getting apprentices' laptops on a version that matches most of our production apps. have also found heroku db pulling and pushing from 1.9.3 on laptop to 1.9.2 on app causes problems with taps: time columns bomb out.
Updated the RVM install script, the original was out of data causing all rails and rvm commands to use wrong locations
