Bug: server constructor defaultOptions throwing error on start

[zpnk]

Was playing around with Central and got this error when starting the server:

/central-demo/node_modules/central/server/server.coffee:28
      this.expressApp.set('views', this.options.viewsPath);
                                               ^
TypeError: Cannot read property 'viewsPath' of undefined

It looks like server.coffee calls _.extend on line 20 with arguments in the wrong order:

@options = _.extend(options, defaultOptions)

Simply switching them to place defaultOptions first fixes the issue:

@options = _.extend(defaultOptions, options)

Server.configure has the same call on line 33, with the correct order.

Edit: PR up.
