Fix broken menu items due to Package Control install directory

The default Package Control channel listing for this package uses the name "Simple Print Function". *(I assume it was changed due to their don't-use-"sublime"-in-names policy?)*

Unfortunately that means it installs  to ${packages}/Simple Print Function/, breaking the menu links to the readme and default settings.

I don't know if there's a way to set a different installation directory, or if you are going to keep the twin naming conventions, but as a temporary solution I updated the menu settings.
