We've recently began to keep our Jenkins configuration on SVN. This causes an uncheked exception when adding the promotions, because subversion adds a .svn directory inside promotions and PromotedBuildsTemplateUtils asks for a config.xml file inside every folder on promotions so, when it reaches .svn, the FileInputStream throws a FileNotFoundException which is propagated later on.

Small fix in the form of a PR following shortly.

(btw, feel free to edit the JIRA as needed, was a bit unsure about cataloging the issue as a bug or as an improvement and also with priority..)
