Various improvements and fixes for Contracts resource.

## Added

### Contracts

* Added `can_have_contract_lines` to the Contracts resource to indicate if the contract can have contract line items added.
* Contracts that have `can_have_contract_lines` as `false` will have an `application_id` associated to it on the Contract resource.
* Contracts that have `can_have_contract_lines` as `true` will not have an `application_id` associated to it on the Contract resource, but will have Contract Line Items attached.

## Fixed

### Contracts

* An `end_date` is now required when `month_to_month` is `false`.
* The field `native_currency` is now required.
