Remove backticks

[KyleAMathews]

Not supported on older versions of node.

Also in serve.js:

handler(request, reply) {

should be

handler: function(request, reply) {

no?

I tried v0.6.2, changed all the backticks and this handler function, got the server to run, but got an error on on the client bundle.js not found.

I fixed a number of things in f07e39c

Can you try the changes and see if it works now?

Why aren't these being transpiled using babel?

[gesposito]

Should be related to #54

[KyleAMathews]

Compiling everything now with Babel.
