OSX menu should have link to data & tools directory

My last comment from MB-7073:

This is actually a problem that I have seen from many users. I think we should add some way to be be able to see the location of your data directory in osx. In some cases I have seen that people will accidentally look in their root directory instead of their home directory and in the case of Tony he had multiple drives which made it a little bit more unclear as to exactly which directory he needed to delete. I am filing a sperate issue for 2.0.1 to have this be easier to do.
