many build tool upgrades:

* upgrade ember-cli
* in dev, char / char source maps
* drop esperanto + es6-module transpiler instead everything uses babel amdStrict
* now builds in node 0.11 0.12 1.x and 2.x
* ember-cli + watchman 3.1 use a single watch root, this dramatically reduces FS handles opened. In-order to not get trolled by rapid `tmp` changes we explicitly ignore it with .watchmanconfig – when facebook/watchman@849cfff we will have an even nicer experience.
