Support for retrieving data as Buffer on a per command basis

Browse Source 
This is achieved by introducing a new option to the createClient method called bufferedInput.
If bufferedInput is set to true, then the returned data will be a Buffer if the command argument passed is a buffer

E.g.
    var redis = require("redis"),
    client = redis.createClient(<port>, <host>, {buffered_input: true});

    client.set("foo_rand000000000000", "OK");

    // The below get request will return a utf8 string
    client.get("foo_rand000000000000", function (err, reply) {
        console.log(reply.toString()); // Will print `OK`
    });

    // The below get request will return a Buffer as the key is specified as a Buffer
    client.get(new Buffer("foo_rand000000000000"), function (err, reply) {
        console.log(reply.toString()); // Will print `<Buffer 4f 4b>`
    });
    client.end();

This may also be set to `javascript`.
* `return_buffers`: defaults to false. If set to `true`, then bulk data replies will be returned as node Buffer
objects instead of JavaScript Strings.
* `buffered_input`: default to false. If set to `true`, then data replies will be replied as node Buffer objects
if the input arguments are passed as a Buffer object. This option will let you retrieve data as a node Buffer object
or as string on a per command basis, unlike the returnBuffers, which applies to all the commands
E.g.
var redis = require("redis"),
client = redis.createClient(<port>, <host>, {buffered_input: true});
client.set("foo_rand000000000000", "OK");
// The below get request will return a utf8 string
client.get("foo_rand000000000000", function (err, reply) {
console.log(reply.toString()); // Will print `OK`
});
// The below get request will return a Buffer as the key is specified as a Buffer
client.get(new Buffer("foo_rand000000000000"), function (err, reply) {
console.log(reply.toString()); // Will print `<Buffer 4f 4b>`
});
client.end();
`createClient()` returns a `RedisClient` object that is named `client` in all of the examples here.
