Merged in cwalther/cwe/launcherstatusmessagecrash (pull request #38)

Don't crash the launcher when the HTTP request for getting the server status message fails

This should fix the crash in UruLauncher.exe after starting UruExplorer.exe, reported by Treehugger at http://forums.openuru.org/viewtopic.php?p=8976#p8976 . It is the same issue as addressed in pull request #31 for the login dialog.

Untested because testing it is hard when the launcher patches itself out.
