got rid of the command, key, filtered ifs, settings, conditional expression.

Left with alert which should be fixed by #1606362: Use throw when an ajax error occurs and extend JavaScript's Error object/#1232416: Drupal alerts "An AJAX HTTP request terminated abnormally" during normal site operation, confusing site visitors/editors.
And a couple of make a function within a loop warnings.

works good, thanks :)

It does, manage display options for fields, autocomplete, and some other places :)

core/misc/ajax.js: line 87, col 78, 'message' is defined but never used.
