[Python-ideas] More friendly access to chmod

[Mahmoud Hashemi]

Seems like the committee has some designs after all?

FilePerms
<http://boltons.readthedocs.org/en/latest/fileutils.html#boltons.fileutils.FilePerms>
is tested, on PyPI, and is even 2/3 compatible. And notice the lack of
"chmod" as a noun. ;)
