Patch for NPE when checking for version

What steps will reproduce the problem?
1. block access to the update site (http://dl.dropbox.com/u/46373738/upd) but 
have an active connection. I found this before I had accepted terms at a hot 
spot
2. run ant with default target (run) in 
http://raptor-chess-interface.googlecode.com/svn/trunk/raptor dir

What is the expected output? What do you see instead?

was throwing NPE with stack trace, now with this patch, it alerts that there 
was an error contacting server (I default to setting a "ready-to-update" to 
true in case that has down stream effects.

What version of the product are you using? On what operating system and
what environment?

Minor annoyance when initally building, but for a newbie, can be concerning.
