granular permissions - updated Tools

Updated all scripts appearing on the tools page
to respect a granular permission defined for
each of them.

The tools menu and home page have been changed so
that only the specific tools that a user has
access are displayed.  This is simple, but depending on
the module and circumstance, it may be better to
display functions that the user has does not have
access to, but disable the links and do some sort
of visual styling to indicate that a function exists
but requires additional privileges to access.
