This adds a page userweek.txt, it is based around a stripped down version of week.php but displays all the bookings for a particular user. This is both bookings made by the user, and bookings with a name that matches the shortname of a course which the user is enrolled on (this sounds a bit complicated, but if you make booking names match course shortnames it will make sense)

Any user can look at their own timetable, users with block/mrbs:viewalltt can look at any user's timetable.

This patch doesn't create any links anywhere to userweek.php (except self-referring ones), it is easy to add a link in any menu- just linking to userweek.php will give users their own timetable. I have played with user/view.php in order to override the 'current location' to display a room name and a link to the timetable, I'll upload that later
