Allow sending of metadata with sendFile

[samsont]

When you send a file: added the ability to send metadata with the file. The functionality was already in place, just added a spot for the additional data.

I like this. @latentflip?

i would rather call metadata the passed parameter everywhere instead of additionalData

[samsont]

I agree with the comment on metadata. The challenge is that on the receiving side, there already is a variable called metadata. (https://github.com/otalk/filetransfer/blob/master/filetransfer.js) . There is a metadata.size and a metadata.name. I access the information I proposing to add as: metadeta.additionalData,

A simpler thing to do might be that instead of using what I wrote:
Peer.prototype.sendFile = function (file, metadata)
Instead to use
Peer.prototype.sendFile = function (file, additionalData)
to keep the same name all the way through.

If I made that change, might that be ok?

Thanks!

I think its safe to call this metadata, this should not conflict with the use of that name in filetransfer?

Any plans on merging this change? It has been two years, so I am curious. I want this change.
