For example, the previous title for the tiddler containing the editor
types tab of control panel was
“$:/core/ui/ControlPanel/Advanced/EditorTypes”. We’re now removing the
“Advanced” portion, so that we don’t have to rename tiddlers like this
if we move them around between tabs
By rearranging the `[all[]]` operator we are able to ensure that shadow
tiddlers get processed before ordinary tiddlers. This makes it easier
to create custom stylesheets that override the core.
