Autotest regexp patch
Created by: JonRowe
The regular expression in rspec-core for matching failed specs with autotest fails when using coloured output.
This causes autotest to be unable to recognise when specs have failed, causing additional reruns of the entire suite and, when using auto feature functionality, for cucumbers to be run prematurely.
This pull request adds a spec test proving the failure of the regular expression (79076fd1) and then a modified regular expression (88af1080) that will match both coloured and plain output.
This closes issue 251
Additionally this pull request ignores .rvmrc files from git allowing individual authors to maintain independent rvm configurations. (1bf1edfd)
