* feat: inform child widget to do some custom cleanup
* fix: type
* refactor: restore old removeChildDomNodes
* refactor: make destroy() a separate method
* refactor: make destroy call removeChildDomNodes
* refactor: call destroy instead of removeChildDomNodes in each core widgets
* fix: refreshSelf does not mean destroy
* refactor: use old var insteadof const
* docs: about subclass
* Make classic storyview work in new windows, too
* Make pop storyview work in new windows, too
* Make zoomin storyview insert and remove animation work in new windows, too
... this makes the animation when inserting tiddlers / navigating to tiddlers in the pop storyview less jumpy
it simply sets `overflow-x` to `hidden` for the time of the insert-animation
There are still some warnings about making functions in a loop, but
I’ll fix those as a separate pull request because the fixes are more
than typographic errors.
