A few minor improvements

Inventory.prototype.typeName method

Add optional callback to Peer.prototype.sendMessage

Get rid of deprecation warning caused by node-buffers library.

The changes to node-buffers look good, however this references an unpublished master branch. There are a few open issues, #52 and #32 with node-buffers already. I believe we only use a small portion of the implemented methods, so we may be able to make this a part of this codebase, since we're also adding the skip method. However we can take care of this in another PR as well as the deprecation warnings.

Thanks for the comments, will update the PR tomorrow.

Any update? Will this ever be approved and merged?

[braydonf]

Needs a rebase on master. It would be good to fix the issues related to buffers in a released version instead of pointing to master branch. Preferably we could bring in what we need from buffers into this project, since there are only a few methods we're using, this could be handled in a separate PR.
