Added Woodman to framework. Woodman removal handled in optimizer

The Woodman library should be referenced with:
 "joshlib!utils/woodman"

That library is thin wrapper around the actual Woodman library that
disables traces from the "joshfire.framework" namespace by default so
that apps that reference the framework do not get bombarded by traces
from the framework classes (once we have those traces, that is).

The optimizer now accepts two more optional parameters:
- minify: a boolean flag to minify the code or not
- traceLevels: a comma separated list of trace levels to keep in the
resulting code (Woodman).

By default, the optimizer minifies the code and removes all references
to Woodman from the code.
