.check-column select all should not toggle disabled inputs

[ragulka]

In common.js, starting on line 401 (https://core.trac.wordpress.org/browser/tags/4.2.2/src/wp-admin/js/common.js#L401) there is a common select/deselect all behaviour handler.

Currently, it only filters the checkboxes by looking if they are :visible, but it should also check for :disabled as it makes no sense to select/deselect via select/deselect all if the checkbox itself is disabled.

Disabling the checkbox is a valid use case for plugins that may want to show a table row, but disable editing/deleting it.

This section of common.js also addresses selecting multiple by use of shift+click. This patch corrects both the use of the select all checkboxes as well as shift+clicking.

Admin: when toggling select/deselect "all" via JS - :visible needs to be bound to not toggle disabled inputs.

Props tywayne.
Fixes #32309.
