LoadError when requiring twitter-text as a dependency

[sferik]

The t gem depends on twitter-text to extract mentioned screen names from Tweet text.

Five separate users, all on different operating systems and Ruby versions, reported a LoadError on the line where I require 'twitter-text'.

Originally, I assumed it was an environmental issue, since I was unable to reproduce the problem on my machine, however, when I released a version of the gem (0.9.4), which lazy-loaded twitter-text, users reported the problem had been fixed.

As you can see from this GitHub compare view, the only difference between version 0.9.3, where users were reporting a problem, and 0.9.4, where users reported that it was fixed is the lazy-loading of twitter-text: https://github.com/sferik/t/compare/v0.9.3...v0.9.4

Again, I am unable to reproduce the error, but I believe that there is a problem with requiring twitter-text as a dependency on some systems, which I thought you'd want to know about.

I am considering reimplementing the extract_mentioned_screen_names functionality that I'm using from twitter-text within the t gem, however I'd prefer to depend on twitter-text than maintain that code myself.
