Fixed invalid html (missing closing tags) in rules description.

@KengoTODA: Would it be possible to take a look at or merge the changes?
We need the description in a proper format as we want to display it inside a html page.

My changes do not cover the whole faulty descriptions yet, but I will continue fixing if I get some response to this issue.

Thank you!

It is OK to merge this PR, however, these files are generated from message.xml in fb-contrib, so coming release will overwrite this change.

Please consider to submit PR to fb-contrib project too.

#336 will update the XML files, so I will merge this PR after we merge #336 to the main branch.

Thank you.
I will also try to file a pull request in the source project, so we do not lose the fixes in future versions.

Hi @koseduhemak, could you merge origin/master to your topic branch, and resolve the conflict?
We updated the findsecbugs so XML generated based on it needs to be updated.
