Two versions of a startup page that will attempt to first load the Welcome

Browse Source 
Guide locally (file://) and upon failure will load it from svn.berlios.de.
Once either of these files are inserted into browser.jar's content/browser,
it can be accessed via chrome://browser/content/<filename>. This will allow
BeZillaBrowser to be installed in any location and still be able to access 
that file. Thanks to Ryan Leavengood and mathewblack for the files!
