bug 335 - making sure it's possible to install from .apm files again. The UI needs improvement. Robustness could also be improved. May need to handle the case when there is a later version of a package in the packages directory than in the apm_workspace dir
Check whether the user has a private calendar now performed calendar_have_private_p - this is package-agnostic, so only create one private calendar per user.
Adding the ability to display a static html page instead of the installer if there is a database problem - useful for production sites. Must be enabled manually by the admin by renaming a file. Bug #156
