Implement Match

[kevinburke]

I'm worried I'm not smart enough to implement Match exec properly; it seems like a security risk.

Punting on this for the moment, the specification is rather complicated

Hey, so today it raised an error when he finds a "Match" directive pattern, maybe can we just pass through it without raise anything ?
Thanks for your package by the way :)

@kevinburke would you consider a PR that made it an option to skip Match exec blocks entirely? I don't need to parse those at the moment, but the rest of the ssh config is useful to me.

@kevinburke ping (about @cv question). I think it's still valid and needs to be handled. Thanks.

Yes I agree. While #45 (#38) does help a little, we loose a lot of functionality that is provided by the UserSettings type. So I think a way to skip Match lines at a higher level would be good, as long as Match is unsupported and results in failure to parse config -- a bool in UserSettings?
