new mod_commands release, minor bug fix

The long-standing manageWindow command bug has now been fixed in the new release (0.0.1) of mod_commands package. Seeing as I am planning on doing more releases shortly dealing with more major changes in the application, I've decided to keep this one as a module-only release (no bsheet package release). Those who wish to obtain this bug fix before new bsheet releases come out, they'll need to download release 0.0.1 of mod_commands and unzip it in their Bean Sheet module directory.
