Minor release, June 28, 2012

A few minor bugs squashed:

• Certain reports were showing content for all hosts where only certain hosts were selected.
• The Mongo datasources were using the properties mongo.user and mongo.pass instead of the documented properties mongodb.user and mongodb.pass. Now both sets of properties work.
• Corrected an issue where some mails systems (mostly Exchange) encoded the ACK message in a way that caused the reply not to be understood.
• Corrected an issue where reports displayed as HTML on recent versions of Chrome would display an error.  The requirements for the Content-Disposition header in Chrome changed – reports now conform with the new requirements and work correctly.
