Add jQuery 4 compatibility

[vpavic]

The latest release (1.3.4) does not appear to be compatible with the recently released jQuery 4.

While attempting to upgrade, I'm seeing the following error:

Uncaught TypeError: _.isFunction is not a function
    parse bloodhound.js:702
    Bloodhound2 bloodhound.js:836

Looking at the jQuery 4 release announcement blog post, there are a number of previously deprecated APIs that have been removed:

Deprecated APIs removed

These functions have been deprecated for several versions. It’s time to remove them now that we’ve reached a major release. These functions were either always meant to be internal or ones that now have native equivalents in all supported browsers. The removed functions include:

jQuery.isArray, jQuery.parseJSON, jQuery.trim, jQuery.type, jQuery.now, jQuery.isNumeric, jQuery.isFunction, jQuery.isWindow, jQuery.camelCase, jQuery.nodeName, jQuery.cssNumber, jQuery.cssProps, and jQuery.fx.interval.

Use native equivalents like Array.isArray(), JSON.parse(), String.prototype.trim(), and Date.now() instead.

[ivanrovira137]

I have modified the 1.3.4 version to be compatible. Here it is. Just use a comparator with the original version to see what have changed.

• Parche local de compatibilidad con jQuery 4:
• • Sustituidos usos retirados en jQuery 4: $.isArray, $.isFunction, $.parseJSON y $.proxy.
• • El helper bind conserva el comportamiento de preaplicar argumentos (equivalente a $.proxy(fn, ctx, ...args)).
• • Ajustado spellcheck a string "false" para evitar warnings de jQuery Migrate sobre atributos no booleanos.
• Este parche se mantiene minimo y acotado para no alterar la semantica funcional del plugin.
