Cleans up ends of scaffold files

Scaffolding.CodeGen.codegenDir no longer removes the final eol. Input files that
had extra eols have had them removed. With these changes, the generated files
are now more identical to the inputs:

    $ diff foo/LICENSE scaffold/LICENSE.cg
    4c4
    < Copyright 2012, foo. All rights reserved.
    ---
    > Copyright ~year~, ~name~. All rights reserved.

Additionally, initial commits of changes to a new project's files aren't
littered with "\ No newline at end of file". Maybe other people don't have this
problem, but vim auto-adds eols to files that lack them...

        Adds newlines to files that need em.
