Support server weights for XMemcachedClientBuilder

[GoogleCodeExporter]

What steps will reproduce the problem?
Try to specify the weights of the servers (see 
https://code.google.com/p/xmemcached/wiki/Spring_Integration)

What is the expected output? What do you see instead?
XMemcachedClient created with weights, not possible to specify them in 

What version of the product are you using? On what operating system?
3.2.1

Please provide any additional information below.
My hack to get weights to work is to rewrite the factory and check the config 
before initializing the XMemcachedBuilder (since as you pointed out, there is 
no getter/setter for weights).

Something like:

        int[] weights = null;
        if (conf instanceof XMemcachedConfiguration) {
            weights = ((XMemcachedConfiguration) conf).getConvertedWeights();
        }

        MemcachedClientBuilder builder = new XMemcachedClientBuilder(addrs, weights);

I allowed the weights to be passed as a comma separated list of integers, and 
getConvertedWeights converts the comma separated list into an int[] (if the 
string is null or empty null is returned).

Code in trunk. Instead of coma separated list an array of int value has to be 
provided. In Spring xml it can be achieved using list tag:
<property name="weights">
  <list>
    <value>4</value>
    <value>8</value>
  </list>  
</property>
