aglio-theme-olio@1.6.3 has outdated dependencies

Hi, during intstall of aglio I get the following deprecation warnings (shown here from `yarn` since it displays the best debugging info:

```
[1/4] 🔍 Resolving packages...
warning aglio > aglio-theme-olio > jade@1.11.0: Jade has been renamed to pug, please install the latest version of pug instead of jade
warning aglio > aglio-theme-olio > jade > transformers@2.1.0: Deprecated, use jstransformer
warning aglio > aglio-theme-olio > stylus > glob > minimatch@0.3.0: Please update to minimatch 3.0.2 or higher to avoid a RegExp DoS issue
```

Unfortunately, I am not able to find `package.json` for `aglio-them-olio` here, even though https://www.npmjs.com/package/aglio-theme-olio states this is the correct repository.

Could some of you please make a PR and perhaps merge it?

Start by locating the aglio-theme-olio package.json referenced by the npm repository link and inspect the dependency tree producing the yarn warnings. The work is done when the Jade, transformers, and vulnerable minimatch warnings are addressed and installation completes without those deprecation warnings.
