Pass headers to knox-mpu and auto detect content type if not set

[evert0n]

This is a prop to add support to automatically set the Content-Type and pass headers to knox-mpu

Related to issue #1 and http://stackoverflow.com/questions/25206528/how-to-add-acl-and-content-type-parameters-when-using-skipper-s3

Checked in knox-mpu and seems that there is no need for changes.

The mime package is also used with knox but only in a call to putFile.

It would be nice if we could have some tests for this skipper-adapter-tests, but that's a bit of a tall order at the moment. I tested locally and it looked good. Thanks!

This looks like it's fixed, but it's still confusing people largely because I don't think there's documentation for it. (e.g. #26 and even an alternate repo). I can fix the documentation if someone explains to me how exactly to use this fix. I think you need a headers member of the options object, and inside that header parameter you need to somehow specify 'public'. How does I?

Aha. Found this
