Update the core commands to match the latest IRI 1.8.1 release

[pdecol]

The core commands implement the API endpoints which are provided by IRI and are contained in the StrictIota class. I compared the current implementation with the latest IRI 1.8.1 release (https://github.com/iotaledger/iri/blob/v1.8.1-RELEASE/src/main/java/com/iota/iri/service/API.java). The following changes are needed to get StrictIota up to date.

Missing commands:

• getNodeAPIConfiguration: This will be needed for Support for "chunking" requests with size limit #138
• getMissingTransactions

Missing parameters:

• getBalances: tips is missing as an optional parameter. references is new in the response and could be added to the response filter.
• getTransactionsToApprove: references is missing as an optional parameter.

Changed fields in the response:

• getBalances: milestone (type: Address) get removed and milestoneIndex (type: int) got added to the response. Shall we remove milestone? Or keep both to ensure backwards compatibility?

Fields that I would add to the response filter because without these values in the response the API call is useless:

• wereAddressesSpentFrom: states
• checkConsistency: state

Furthermore for all commands :

• In the source code are references to https://iota.readme.io/docs/ As this website is not used anymore this should be updated to respective references in the official docs https://docs.iota.org/docs/node-software/0.1/iri/references/api-reference

Let me know what you think. I planning to implement this myself and I will open a pull request soon.

The IRI team needs this issue fixed for our regression tests.
