prototype Merge Request #1: Upgrade jnotify to 0.94 to support 64-bit linux (rejected)

Jnotify 0.93 silently crashes the JVM on 64-bit systems.

This upgrades to 0.94 and selects the correct native lib via ANT. The binaries are from the jnotify sourceforge download page, you can verify them. Ideally we should patch jnotify as well to output an error message if it can't load the native lib, I'll try that tomorrow.

Screwed up the first attempt, see merge request #2 instead.
