Several Small Code Fixes

Hi all,


While building a custom version of Roller for our client, I went through
Roller's source code using FindBugs and I have several fixes to commit.
Those are spread all over the source files, mostly smaller fixes like
some misspelling that lead to NPEs and so on.

I think it would be way too time-consuming to create a ticket for each
fix. Would it be okay for you guys if I create one ticket for all those
findbugs suggestions (one to rule them all)?


Thanks,
Matt
