Fields can now be skipped with the `#[graphql(skip)]` annotation. Note this
doesn't really make sense for GraphQLInputObjects so this isn't supported there.
Fixes https://github.com/graphql-rust/juniper/issues/220.
* Added trait to convert a custom error type into a FieldError
* Convert the error type of the gql fields if it implements IntoFieldError
* Added test case to check if custom error handling works
* Added to changelog
This makes it so people using git dependencies know what has changed. It also
gives a spot to make a running changelog so when we do a release we can just
copy and paste.
