Previously, the `rand` and `rustc-serialize` dependencies were optional except they were required for the `bigint` feature. Make the dependency on the `rand` crate optional in all cases. including when the `bigint` feature is selected. Some of the tests for the bigint feature are randomized so, while `rand` is now an optional dependency, it is a non-optional dev-dependency. Similarly, make the dependency on the `rustc-serialize` crate optional in all cases, including when the `bigint` feature is selected. |
