/**
* Language Select Code for non-Widget users
* @args is a hash array of options, which accepts the following keys:
* ‘type’ – one of the values: ‘text’, ‘image’, ‘both’, ‘dropdown’ and ‘custom’, which match the choices on widget admin page.
* ‘format’ – needs to be provided if ‘type’ is ‘custom’. Read help text to this option on widget admin page.
* ‘id’ – id of widget, which is used as a distinctive string to create CSS entities.
* @since 3.4.5 type of argument is changed, compatibility with old way is preserved.
