Error if you put a space at the end of the RAB project name

I was just helping a RAB user who had a problem with creating a RAB project because he put a space at the end of the name. Fortunately, I was able to see that that was the cause of the problem by looking in the error log file. I think it would be best to either automatically trim leading and trailing spaces or tell the user that they are not allowed, rather than quietly failing.
