_serialize method
This commit adds a utility method as a counterpart to the _unserialize utility method, allowing users to manually serialize data themselves before sending it to Redis. This could be useful for calls going through EVAL, as phpredis can't automatically serialize/unserialize in that case. Addresses phpredis#431

### _serialize
3144+
-----
3145+
_**Description**_: A utility method to serialize values manually.
3146+
3147+
This method allows you to serialize a value with whatever serializer is configured, manually.
3148+
This can be useful for serialization/unserialization of data going in and out of EVAL commands
3149+
as phpredis can't automatically do this itself. Note that if no serializer is set, phpredis
3150+
will change Array values to 'Array', and Objects to 'Object'.
3151+
3152+
##### *Parameters*
3153+
*value*: Mixed. The value to be serialized
3154+
3155+
##### *Examples*
3156+
~~~

$redis->setOption(Redis::OPT_SERIALIZER, Redis::SERIALIZER_NONE);
3158+
$redis->_serialize("foo"); // returns "foo"
3159+
$redis->_serialize(Array()); // Returns "Array"
3160+
