Title: Fixed WAIT_TIMEOUT environment variable casting issue

I've encountered an error when I tried to set `WAIT_TIMEOUT` from command line or `env.rb`:

undefined method `zero?' for "3.0":String (NoMethodError)
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/timeout.rb:53:in `timeout'

I've found casting `ENV['WAIT_TIMEOUT'].to_i` solves the problem, but I'm not a rubist, so my solution may be wrong. Please review it closely.

Here's my system configuration:
* `Mac OS X 10.7.2`
* `ruby 1.8.7 (2010-01-10 patchlevel 249) [universal-darwin11.0]`
* `cucumber 1.1.4`
* `frank-cucumber 0.8.7`
