Add a test for zip installations 

Need a test that installs from zip in npm, such as

```
 ""Modernizr": "https://modernizr.com/download?adownload-filereader-input-inputtypes-localstorage-placeholder-sessionstorage-setclasses-dontmin.zip"" 
```

when you run 

```
npm install https://modernizr.com/download\?adownload-filereader-input-inputtypes-localstorage-placeholder-sessionstorage-setclasses-dontmin.zip --save 
```
