Missing initialization of transifex object in "particular resource" example

The example code in "Retrieving a particular Resource of a Project by its identifier (slug)" currently gives:
```
runnerscripts/update_locales_from_transifex.rb:5:in `<top (required)>': undefined local variable or method `transifex' for main:Object (NameError)
	from /home/jason/.rvm/gems/ruby-2.0.0-p247@greasyfork/gems/railties-4.0.3/lib/rails/commands/runner.rb:51:in `eval'
	from /home/jason/.rvm/gems/ruby-2.0.0-p247@greasyfork/gems/railties-4.0.3/lib/rails/commands/runner.rb:51:in `<top (required)>'
	from /home/jason/.rvm/gems/ruby-2.0.0-p247@greasyfork/gems/railties-4.0.3/lib/rails/commands.rb:84:in `require'

	from bin/rails:4:in `require'
	from bin/rails:4:in `<main>'
```
Just forgot to initialize the "transifex" variable.
