Switched some warnings over to debug, as they always occur when installing a bundle created using the bundle plugin and the log message is confusing (it doesn't tell the user if/why they should be concerned about this issue - in fact I can't really tell why it's a warning). Also tweaked a couple of info messages to give the user better feedback.
