Use \ instead of concatenation for multi-line strings

[GoogleCodeExporter]

When pressing <Enter> inside a string literal, js2-mode currently uses 
string concatenation to create a new line:

var x = 'first line'
    + 'second line';

It would be better - in terms of number of characters, readability and 
performance - to use a backspace to escape the new line instead:

var x = 'first line\
second line';

I agree that it'd be nicer, but I can also see cases where you want to indent 
the 2nd line. So I'd vote for one 
default behavior and another key binding for the second.

I can add an option for this.

Performance:  not an issue.  SpiderMonkey and Rhino both collapse string literal
concatenations into a single string literal during parsing.

Here's an attempt at a patch. I haven't written all that much Elisp before, so 
it'll
need a once-over before inclusion, I expect. It's pretty simple though.
