replace user errors with exceptions

Exceptions are better to handle than errors. What I don't like is that
we now have an unfortunate mix of return code and exception signalling
for errors. Some methods still return false for errors while others
now throw exceptions (always returning true otherwise).

remove html_softbreak_callback()

re-declare deprecated function html_edit_form()

* `html_locked()` is used by one third-party plugin (AjaxEdit), fallback should be added.
* `html_insert_softbreaks()` is used by one third-party plugin (TOS, terms of service), fallback should be added.

use Slika for image resizing and cropping

This replaces our own resize/crop function by the Slika library.

use Slika for image resizing and cropping

This replaces our own resize/crop function by the Slika library.

This is not yet ideal, as there is quite a bit duplicated code between
media_resize and media_crop now. Ideally these two should be replaced by
a single method handling both. I'm just not sure where to best put it

Using Slika introduces two new features:

* auto rotation based on EXIF #3059
* support for webp #3238
