Before layers were sometimes only activating the non strict
version of smartparens. Also some were only disabling
the non-strict version leaving some of the smartparens
advices intact.
With this PR, all layers set the right version of smartparens.
Also if the layer is trying to disable it a standard function
will now take care to disable all versions of smartparens.
Add a full/minified transient state toggle.
Grouped backend transient state key bindings by column.
Moved the html/init-web-mode :init section before the :config section.
