Comment:

 The new patch sets an option called "theme_switched" in `switch_theme()`
 and then checks for it on init and fixes the widgets.  It also maps
 leftovers to sidebar 1 instead of init, so if the old theme had 4 sidebars
 and the new has 3 it will do this:

 * Old A -> New 1
 * Old B -> New 2
 * Old C -> New 3
 * Old D -> New 1

 Westi: It still doesn't handle preview, but but it handles the actual
 switch pretty nicely.
