Supports Selenium 2.45, TAB, BACKSPACE, Selenium Grid File Upload

[sglebs]

• supports TAB and BACKSPACE
• fix for Safari (timing)
• fix for file uploads with Selenium Grid
• FitNesse 20150424
• Selenium 2.45 (needed for recent versions of Firefox)
• had to upgrade some components due to Selenium 2.45

Feel free to retain the original FitNesse (I had issues with Guava too) but Selenium 2.45 support is a must for the latest Firefox. TAB and BACKSPACE support is also a must. The Selenium Grid file upload support is also a must if using the grid with tests that upload files to web forms.

Hello Marcio, thanks for your contributions! Sorry for not responding earlier.

It would make things somewhat smoother if various changes were presented in separate pull requests - some are probably more controversial than others :)
