The original timesheet plugin was developed for an (very ancient) beta of sunbird. Now that a stable release exists, we need to adjust the plugin for this release.
The difference between the beta and the stable release is a completely revised ui. Not only the views but the edit windows has changed dramatically aswell.

Branch the trunk to an 0.3beta bracnh

Check if the venkman debugger is finally ready for sunbird (cross my fingers)
