Pushing my changes:
Fixes memory leaks when using Garbage Collection.
Fixes various other memory leaks.
Implement finalize methods for Garbage Collection on the PrefPane.
Use level indicators instead of progress indicators for the paddles.
Reference Xcode projects in Xcode projects that use files from other Xcode projects. This means we don't have to track built files outside of Xcode.
Add a top-level Xcode projects that references the other Xcode projects (either directly or indirectly).
Have the force feedback plug-in have the right extension when being built.
Have the feedback plug-in be a four-way universal binary.
Fixed a few uninitialized variables.
Use [pool drain] instead of [pool release]
Restrict what gets exported in the force feedback bundle.

Removed code-signing as I don't have the right key.
