- Expose remote shortcuts for the `fs`, `os` and `child_process` modules.
- Expose the `url` and `timers` modules(the browserify versions)
- Add `process.crash` and `process.platform`
This change gives sandboxed renderer scripts a similar structure to what already
exists in the lib/{browser,renderer,common} directories.
It also allows sandboxed renderer initialization to share more code with
non-sandboxed renderers (ipcRenderer is now imported directly from
lib/renderer/api/ipc-renderer).
