v1.4.0

Fixed

• Added proper types for helper functions that support array in the first argument.
• Asset_Manager_Preload::set_asset_types() should return an empty array if no valid arguments are passed.

Changed

• Migrates code into the Alley\WP\Asset_Manager namespace. Legacy classes such
  as Asset_Manager_Scripts and Asset_Manager_Styles are aliased to their new
  namespace for backward compatibility. Helper functions are left un-namespaced.
• Adds a dependency on Composer autoloader. For submodules, you can track the
  production-built branch of the plugin or any tagged release (which will be
  built) to include the dependencies.
