- Made the calendar module accept a $date parameter such that you can jump directly to a certain date in the archives. Also made the calendar link to itself such that it is self-contained. - Code beautifications: quoted a lot of arrays, removed dead code and simplified a few things. - Replaced the Calendar class by one function "calendar_display": using a class (or class instance, or object) doesn't make sense in the archives' case. - Renamed "calendar.module" to "archive.module". - Fixed a /problem/ with node settings not always being saved like expected. - Reorganized the user menu: renamed a couple of links for clarity and structure. - Fixed a few typos.
