bug#14339: 24.3.50; [patch] ff-find-other-file doesn't understand Objective-C

[Ivan Andrus <darthandrus@gmail.com>]

Below is a simple patch to support Objective-C files (.m extension) for
ff-find-other-file and a sample ChangeLog entry.  There are Obj-C files
in the Emacs distribution and I think this would be useful to several
people.

I have copyright assignment papers on file.

Thanks,
Ivan
