Merge branch 'ftp-2394'

typo

bump Twisted dep to 11.1.0, thus simplify IntishPermissions

test_ftp: fix comparison against integer

Fix ftp 'ls' to work with current Twisted-15.0.0

refs ticket:2394

It's kind of a hack, but Twisted changed the API and I couldn't find a
cleaner way to detect which form of "permissions" value the Twisted FTP
server wants.

I've manually tested it against 14.0.2 and 15.0.0.

Merge pull request #149 from warner/mutable-2034

use more servers for test_mutable.Update, to test #2034 properly

use more servers for test_mutable.Update, to test #2034 properly

Add a test, add missing imports. refs #2388

This tests ftpd, but not sftpd. Doing this sort of test on sftpd
requires the creation of a valid pubkey/privkey file pair, which is more
work than I want to do right now.

init_ftp/init_sftp were changed to interpret the configured
accounts.file as relative to the node's basedir, with
abspath_expanduser_unicode(accountfile, base=self.basedir).
This would happen naturally in a real node, since it os.chdir()s
to the basedir before doing anything. But tests don't do that.
