Reflect ActiveRestClient's deprecation

[andyjeffries]

Thank you for having documentation pointing to ActiveRestClient. Unfortunately, the owners of the ActiveRestClient repository stopped supporting it about 8 months ago, so I forked it (I was the original author of most of the codebase) and am now supporting it under the name "Flexirest".

https://github.com/andyjeffries/flexirest/blob/master/Migrating-from-ActiveRestClient.md

I've updated the README to reflect this so users don't keep using ActiveRestClient.

Thanks!

By the way, Flexirest also supports per model authentication (if it's accessing two different APIs for example, each with different credentials) - https://github.com/andyjeffries/flexirest#api-auth.

And it will support your new :digest option, when it's available ;-)

Areas that Flexirest beats ActiveResource :-D
