Fix dolphin places config (user-places.xbel)

Existing dolphin configs can be incorrect for two reasons:
- Instead of the class identifier, a * was incorrectly entered in the home@server URL.
- If the student has changed classes, the old class name is still in the home URL.

lmn-patch-dolphin.sh no longer enters a * in the home@server URL.
lmn-fixhome-dolphin.sh will fix existing configs.
