TorBrowser bundle preferences & bookmarks

When updating the TorBrowser bundle on Mac OS X, the Tor Browser bookmarks and preferences for the applications and extensions (Vidalia, Tor Browser, NoScript, etc.) are lost. This is a result of all this information being contained within the TorBrowser "package" on Mac OS X, which is replaced by the new version and its default contents.

Please provide an installer with the TorBrowser bundle that copies all that information from the existing Tor Browser folders to the new folders.
