subgenerator (endpoint) name validation #540

Hi,
I had an issue when creating a new endpoint with a snake-case name:

yo angular-fullstack:endpoint some-endpoint

Everything was created as expected except fot the variable names introduced inside the generated template files.
Even though the generated routes and filenames work ok with snake-case phrases - in this case:

some-endpoint.controller.js

the name should be formatted as a valid javascript variable in order to avoid these kind of situations:

exports.index = function(req, res) {
  SomeEndpoint.find(function (err, some-endpoint) {

Maybe the callback argument should be filled with the same classnamed version of the name.
