/**
* Threaded class to check for updates in the background.
* <P>
* This is the class that handles the mind control and stuff for
* spying on our users and stealing their personal information.
* A random ID number is generated for each user, and hits the server
* to check for updates. Also included is the operating system and
* its version and the version of Java being used to run Processing.
* <P>
* Aside from the privacy invasion of knowing that an anonymous Processing
* user opened the software at one time during a 24-hour period somewhere
* in the world, we use the ID number to give us a general idea of how many
* people are using Processing, which helps us when writing grant proposals
* and that kind of thing so that we can keep Processing free. The numbers
* are also sometimes used in ugly charts when Ben and Casey present.
