Summary:
This diff adds the ability to add 2 flags to gentest.rb that can help with debugging that I found myself wanting to use:
* The ability to suspend the script. Meaning the chrome browser will pause after running each fixture so the user can inspect elements to see if their html is as expected. Normally, the browser just redirects to the next fixture
* The ability to run a specific fixture instead of all fixtures. I found myself wanting to do this as I was changing one in the previous diff. If the user input is incorrect it just ignores it.
Hopefully this will help make debugging this script a bit easier for noobs like me :P
