Add ability to re-run last test about exunit.el

[ananthakumaran]

exunit uses the compilation-mode, so it supports all the features supported by compilation-mode. You could use g from the compilation buffer to re-run. I always use this, that's why never found the need to add one in exunit itself.

Another person had asked me the same thing, so we could consider adding the command in exunit itself.

Added exunit-rerun in the master, let me know if anything doesn't work as expected

Thanks! I'll check it out and let you know

Thanks! This is fantastic and works basically exactly as I want/expect it to. Already a huge improvement over my previous setup. :)
