Disallow Multiline Strings (no-multi-str)

It's possible to create multiline strings in JavaScript by using a slash before a newline, such as:

var x = "Line 1 \
         Line 2";

Some consider this to be a bad practice as it was an undocumented feature of JavaScript that was only formalized later.
