Fixes file-ordering bug in files loaded from jasmine.yml

On OSX, directory contents are always ordered the same, due to OSX's HFS+ file system. On Linux machines however, directory contents do not have a defined order.

This means every OSX system will run tests in the same order, but different linux machines will run tests in different orders. This pull request sorts the files specified in the jasmine.yml so that the file-order is the same across file-systems.
