One new property for CssDockTitle
StackDockStation no longer sends unnecessary focus request
Merged classes for Java 1.6 and Java 1.5 in one project, and use ANT to ensure the classes for 1.5 are not using features from 1.6.

This should make the maven build much easier.
Updated POM to include src-j6 directory for java 6+ builds.
Removed separate java6 project as it's already included in core.
