Update to latest official build, 2013.11.18.

Update to the latest official build, november last year.

Please also consider tagging. I realize the compiler doesn't employ semantic versioning but either `yyyy.mm.dd` or `1.yyyymmdd.0` ought to work. This is primarily to allow consumers to 1) know how current the compiler is, and 2) lock down on a version.

The version this is replacing is 2013.06.03.
