Merge #411

411: Add licence and description field in index-settings crate r=bidoubiwa a=bidoubiwa

In order for the `index-settings-macro` to be publishable on crates.io, it requires a `description` and `licence` field. 
Unfortunately, the `--dry-run` did not raise that, this lead to a failed publish previously.

```
Caused by:
  the remote server responded with an error: missing or empty metadata fields: description, license. Please see https://doc.rust-lang.org/cargo/reference/manifest.html for how to upload metadata
```
