add possibility to use templates based on https://github.com/BorisMoore/jsrender

Note: https://github.com/BorisMoore/jquery-tmpl is no longer maintained and https://github.com/BorisMoore/jsrender is the replacement for it. jquery-tmpl needs to be adapted to jQuery 4 but that will not happen. Support for jQuery 4 for jsrender might be added soon

BorisMoore/jsrender#377

LGTM, do we need any tests/demo for this functionality?

Shouldn't this be protected against NPEs ?
Both templateBehavior and templateBehavior.getTemplateRenderingCode() may return null.

Checking

[reiern70]

templateBehavior is not null.

protected String $()
			{
				if (templateBehavior != null)
				{
					// warning, the template text should be of the form <a>...</a> in order to work
					String render = "jQuery('%s').data('ui-autocomplete')._renderItem = function( ul, item ) { " // lf
							+ "var content = " + templateBehavior.getTemplateRenderingCode() // lf
							+ "return jQuery('<li/>').data('ui-autocomplete-item', item).append(content).appendTo(ul);" // lf
							+ "}";
					
					return super.$() + String.format(render, this.selector, templateBehavior.getToken());
				}

				return super.$();
			}

adding check for getTemplateRenderingCode

I will check. It seems to work Ok in our application in combination with custom values for autocomplete component.
