Revert "#1199328 by casey, bojanz: Add typehintings to every place which doesn't break the api. KUDOS"

This reverts commit 553f0e80.

#1147326 by becw, dereine: Add a way to reverse transforming of argument values back to the original value, so you can use it for the summary. For example you can have now user: uid as argument but still have nice username urls.

Tweaked the argument init code. When upgrading from D7 Views, it should now correctly move the summary plugin settings as well (making the update completely smooth)

Change the summary form's "Number of records" checkbox to radio buttons, with a description of the default sort order where possible.

Further work on arguments (styling for dependent elements, cleaner validation settings, a few bugs killed)

Fix argument query function signatures. Add update code for override checkboxes. Don't use the overriden values (title, breadcrumb, exception title) if their override checkbox are not checked.

#972620 by dereine: Add an administrative title field for all handlers to make it more possible to distinguish similar fields from each other in the UI.
