Add SelectionListener and KeyListener to events
Recognize 'amd64' arch on OS X
Match other platform cpu checks
Use expand_path to locate JFace JARs

When using Warbler and bundling the swt gem into a JAR,
JRuby was unable to find the JFace JARs, which were collected
using File.dirname. JRuby *could* find the SwtBot
extensions, which were collected using File.expand_path. This commit
simply uses the File.expand_path strategy for both scenarios.
