ENYO-1088: investigation to make Ares work as a Chrome Packaged App

- remove private key & certificate (chrome does not allow loading an
  extension or packaged app whose directory structure contains a key or
  a certificate.
- add 16px & 128px icons (bare minimum to show-up in the new-tab-page)
- add manifest.json (version 2)
- add extension/packaged-app trampoline ext.js (starts Ares via a New
  Tab).
- attempt to fetch service definition from the IDE server only if served
  (not if opened like a static resource, as it is the case when loaded
  as a chrome extension/packaged-app).

Full investigation details in the associated ticked [#ENYO-1088](https://enyojs.atlassian.net/browse/ENYO-1088)

ENYO-1108: introduce FileSystemService

FileSystemService is a programmatic indirection between HermesFileTree
(the widget, soon-to-be-renamed into FileSystemTree) and HermesService,
which implements the Hermes verbs to the (possibly distant) Hermes
server.

Right now, the single FileSystemService implementation is HermesService.

ENYO-1171: Make files GET-able, without JSON intermediate

- GET on a Hermes server now returns the file content
- PROPFIND on a file now returns pathname (like location.pathname)
  usable in a URL.
- PROPFIND on folders return children[] instead of contents[]
- Use proper enyo.Ajax response/error chain
- Use express response.sendfile() rather than poor man's file-magic
