Upgrading Casper to 1.3.2

no issue

- Our new marketplace (gpm) will make heavy use of package.json files
- Full details, spec, and validator are coming soon. In the meantime here's the basics:
   - `name` must be lowercase and hypenated
   - `version` must be semver compliant
   - `homepage` should be a valid URL (GitHub URL is ok)
   - `demo` should be a working Ghost install that uses your theme
   - `engines` should contain a Ghost key indicating which version of Ghost the theme is compatible with
   - `license` is required, we recommend `MIT`
   - `screenshots` should provide a relative path or absolute URL to both `desktop` & `mobile` screenshots
   - `author` should be an object. It must contain an email, and can also include a name and url.
   - the `gpm` object should:
	- indicate the package type (`theme` for now, later `app` or `adapter` etc)
   	- list out at most 2 marketplace categories for inclusion. Categories can be found in https://gist.github.com/ErisDS/d0674f57eaa087c9f92cbfc8e984d2d6 but are subject to change.
   - other fields can be included as per a normal npm package, we recommend including the repostory & keywords with `ghost` & `theme` listed.
