Developers can see Guatemala Tariff Rates [81716168]

Fixed. This was an accidental check-in. Without including 'ruby-', RubyMine issues the warning:
```
Project .ruby-version Settings
Cannot switch SDK. RVM SDK '2.1.3@webservices' wasn't found.
```
but it looks like IDE successfully selects proper SDK and switches to it and everything works fine:
```
[/Users/james/govwizely/webservices]$ ruby -v
ruby 2.1.3p242 (2014-09-19 revision 47630) [x86_64-darwin14.0]

[/Users/james/govwizely/webservices]$ rvm gemset list
gemsets for ruby-2.1.3 (found in /Users/james/.rvm/gems/ruby-2.1.3)

```
