Revert "Handle TOML Library Licensing"

It breaks Hugo, will have to test/investigate.

Erro when building Hugo docs:
```
ERROR: 2016/08/05 11:19:23 site.go:1208: unable to process menus in site config
ERROR: 2016/08/05 11:19:23 site.go:1209: Unable to Cast map[string]interface {}{"pre":"<i class='fa fa-space-shuttle'></i>", "weight":-20, "url":"/commands/", "name":"Hugo Cmd Reference", "identifier":"commands"} of type map[string]interface {} to []interface{}
```

This reverts commit 7402856f06.
