Dacosta'd

• fiveby now has a disableBrowsers option that will disable selenium completely and remove the need for browser config. This is for folks that have no need of browsers but love fiveby
• the presence of the browser argument in the fiveby callback will determine if a browser is spawn regardless of the disableBrowsers flag. This feature is for those that want to mix browser and non-browser testing in the same project
• lots more unit tests and CI goodness
• index split into index and lib/fiveby
• upgraded to selenium 2.44.0
• small bug fixes
