1.0.0.beta3

This release contains a bunch of bug fixes since beta2, as well as some polishing. Some of the changes include:

* A new Flash-based uploader
* New contacts app (import/export vcard still temperamental)
* Updated to Dojo 1.2.0
* Namespace changes (api.* and login.* merged into desktop.*, see this for more details)
* Context menu for window titles and taskbar items (allows you to float windows on top, among other things)
* Word processor has more formating options
* Packages now have version compatibility metadata
* Update manager (won't work until the new site is finished)
* Theme polishing
* Apps now show currently opened file in their window title
* Various fixes to Katana IDE

Also, we've written some new documentation, including an installation guide. Documentation is still a work-in-progress, but things are moving steadily.
