fixes #70.
Merge branch 'master' of github.com:nicksieger/ci_reporter
Works around issue with features that include tables

When using this on a feature that has a table, like:

    Given I input the following:
    | name  |  hedwig |
    | unit  |  inches |
    Then I should be angry

I get an error similar to the one in Issue #21

undefined method `failed?' for #<Cucumber::Ast::Table::Cells:0x00000009db4eb8> (NoMethodError)
