Update KLogger.php

Create a cleaner output for dumping the variables:

before:
--------
2013-06-05 9:22:22 - INFO --> Testing passing an array or object; <pre class='xdebug-var-dump' dir='ltr'>
<b>array</b> <i>(size=2)</i>
  'a' <font color='#888a85'>=&gt;</font> 
    <b>array</b> <i>(size=1)</i>
      'b' <font color='#888a85'>=&gt;</font> <small>string</small> <font color='#cc0000'>'c'</font> <i>(length=1)</i>
  0 <font color='#888a85'>=&gt;</font> <small>string</small> <font color='#cc0000'>'d'</font> <i>(length=1)</i>
</pre>


now:
-----
2013-06-05 9:22:30 - INFO --> Testing passing an array or object; 
array (size=2)
  'a' => 
    array (size=1)
      'b' => string 'c' (length=1)
  0 => string 'd' (length=1)
