Update to v1.4.2.0

A few seconds ago I pushed a new version to the server. Support for Simplified Chinese was added (thanks to ToadLoading (Liu Ding)) and from now on multiple URLs are used for the Internet connection check (http://www.google.com/, http://www.dropbox.com/, http://www.microsoft.com/). Additionally, two bugs were fixed.
