Update README with new DNSChain features

[taoeffect]

For the next release, mention all existing features and new ones:

• Basic Openname Resolver Support.
• HTTPS discrimination
• Redis caching
• Fine-grained and intelligent traffic throttling control on both DNS and HTTP queries
• Super-simple to add support for arbitrary blockchains now via a one-file modular approach.
• NXT blockchain support.
• Complete mocha testing suite.
• icann.dns (retrieve DNS results as JSON via HTTP(S)).
• Ability to specify blockchain configuration file path via the dnschain configuration.
• Huge refactoring for Promise based code.
• Autogenerating TLS key/cert.
• Testing suite with over 73% code coverage.
• Travis CI support.

Anything else I forgot? (Edit: this list is being updated with more items as I think of them and go through the closed issues.)

Complete list for all issues in this milestone.

Anything else I forgot?

Of course, there's @wemeetagain's work on blockchain modularity, and because of that maybe we can also add Nxt support without much difficult via minor modifications to PR #96.

Edit: and a new testing suite.

Edit2: mention icann.dns metaTLD and any other new datasources we add to HTTP API.

I think #60 has been closed as well. @wemeetagain, can you confirm that this is the format for doing that?

config = /path/to/config.conf

[otherblockchain]

config = /path/to/other/config.conf

?

@wemeetagain Nevermind, I confirmed that's working (needed a small fix, done in mocha, so you don't need to worry about it).
