Property Gatherers JavaScript Gatherers

If you select from the main menu Project -> JavaScript Gatherers a dialog will appear where you can create and edit them. In this dialog there is a text editor that represents the body of a function that will receive as a parameter an HTML element or an HTML node and must return the value of the desired property. For example, a property gatherer whose code is return element.innerText; will output the text of the element (emulating the built-in InnerText property gatherer), and one whose code is return element.href; will output the href attribute of the element assuming the element is a link.

When creating a Kind, a property gatherer that returns null will be ignored and won't be listed on the Kind's properties.
