Support reserved words as property names

[moretti]

I'm using Q and some of its methods are reserved words, like catch and finally.

In Q for example you can write:

Q($.ajax(...))
  .catch(function (response) {
    console.error(response);
  });

But this is formatted by js-beautifier in:

Q($.ajax(...))
  .
catch (function (response) {
  console.error(response);
});

Because catch is interpreted as a keyword.

Is there a way to format this code properly without using the square bracket notation (i.e. Q($.ajax(...))['catch'](...))?

Thanks!

Same as #309, #351, #368 but this is another solid description of it. All of these are made more difficult to fix by #200, but not impossible.

Was about to open a ticket for it, here is a testcase at least mokkabonna@1d4f65d

Solution is needed for all kinds of reserved words as method names.
