Utilities.js assumes existence of window global

[cdent]

The Utilities.js file, of the files used to build TiddlyWiki, assumes that there is a global window variable. This is not true in some situations:

• unmocked, independent unit tests
• server-side javascript

It would be best if the last lines of the files were guarded with a test for window being defined and being a dict. Here's the original code.

if(!window.console) {

console = {tiddlywiki:true,log:function(message) {displayMessage(message);}};

}
