sshd_config keys should be case insensitive

[domcleal]

Alexander reported in #13 that sshd_config keys should be case insensitive, so Listenaddress and ListenAddress entries are treated as a single key with multiple values.

Currently Augeas treats path expressions case sensitively, so it may need Raphael's regexpi pathx function and reworking of all the expressions, or a custom aug_match etc.

Yes, *[label() =~ regexp('#{key}', 'i')] could be used, but that would add a dependency on Augeas 1.0.0 strictly. Is that ok?

[domcleal]

@raphink no, both Debian stable and Ubuntu LTS use 0.10.0 still

[raphink]

Right, so we need to wait still.

[domcleal]

Yep, or iterate over the nodes ourselves and do a case insensitive comparison instead of using a path expression.

Fixed in 4b556d0 (1.1.0).
