Calls the JavaScript function, optionally with the given arguments.

If a block is given, the block will be passed to a new JavaScriptGenerator; the resulting JavaScript code will then be wrapped inside function() { … } and passed as the called function’s final argument.

Examples:

# Generates: Element.replace(my_element, "My content to replace with.")
page.call 'Element.replace', 'my_element', "My content to replace with."

# Generates: alert('My message!')
page.call 'alert', 'My message!'
