relax multi_json restriction

[thoughtafter]

Unless there is a reason that twitter requires multi_json >= 1.3 it would be nice to change that to >= 1.2 so that versions of the twitter gem after 2.2.1 are compatible with Rails ActiveSupport 3.1 which restricts to multi_json < 1.3:

https://rubygems.org/gems/activesupport/versions/3.1.8

Or if there is another way to achieve Rails 3.1 support that would be great, especially in the wake of need to upgrade to Twitter 4.

This is fixed in master. I'm not planning to push another release for a little while but you can point to this git source in your Gemfile, like so:

gem 'twitter', :git => 'git://github.com/sferik/twitter.git'
