Support for Vaadin 10 and Web Components

ElementQuery has been rewritten to work with Web Components and the DOM

• $(ButtonElement.class) searches for the tag defined in ButtonElement using @Element("some-tag")
• id("someId") restricts the search to elements with the given id
• attr(name,value) restricts the search to elements with the given attribute value
• first(), last(), all(), get(i) fetches the given matching element
• onPage() resets the search context to the root of the page
• Other methods previously available in ElementQuery were removed

New helper methods added to TestBenchElement:

• getPropertyString(name), getPropertyBoolean(name), getPropertyDouble(name) fetches the property from the element
• setProperty(name,value) sets the property on the element
• callFunction(name, parameters) calls the given function on the element using the given parameters

Support for IE8, IE9, IE10 and PhantomJS was removed. These browsers are not supported by Vaadin 10.

A HasElementQuery interface was added to make it easier to create helper interfaces using element queries.
