                Download a cacert.pem for RailsInstaller
              
          
    Why?

There is a long standing issue in Ruby where the net/http library by default does not check the validity of an SSL certificate during a TLS handshake. Rather than deal with the underlying problem (a missing certificate authority, a self-signed certificate, etc.) one tends to see bad hacks everywhere. This can lead to problems down the road.
From what I can see the OpenSSL library that Rails Installer delivers has no certificate authorities defined. So, let's go fetch some from the curl website. And since this is for ruby, why don't we download and install the file with a ruby script?
Installation

The Ruby Way! (Fun)

Ref: http://babinho.net/2011/05/autocomplete-fields-in-rails-3-1-with-jquery-ui/
To use this I had to download jquery-ui (http://jqueryui.com/download) and select Autocomplete
