window.onload conflicts with other plugins

Hi there,

You have used following code in “wp-code-prettify.php” file

window.onload = function(){prettyPrint();};

which does not let run the window.onload function defined in other plugins/themes activated at websites. This, in turn, breaks the functionality of the website which uses your plugin.
So, you must change that code to following:

function soliOnLoad(func){
			var boliqOldOnLoad = window.onload;
			if (typeof window.onload != 'function') {
				window.onload = func
			} else {
				window.onload = function () {
					boliqOldOnLoad();
					func()
				}
			}
		}
		soliOnLoad(function(){
			window.onload = function(){prettyPrint();};
		});

Above will not cause conflict with window.onload function of any other plugin/theme.
