Catch all exceptions in jansi initialization. Fixes BUKKIT-4936

Both log4j and our own jline/jansi initialization attempt to catch
errors caused by jansi's use of native libraries. However both of them use
the Exception type which does not catch all errors. On Windows Server 2008
R2 Enterprise without installing extra software the required C++ libraries
are not available which causes an error that does not extend Exception. To
ensure we catch all errors I've changed both of these to catch Throwable
instead which gets us a working console minus jansi functionality.
