Usability Improvements

- added support for unused byte recognition in scirpts to make those
bytes appear grayed out.
- added support for hovertext in scripts
- add app.vars to show variables to the users
- made scripting adjustments to get some variables to show up in vars
and others to stop showing up.
Added map reference support in scripts

Scripts can now create a "link" datatype which includes double-click
support for going to another location. Because the link is read only
once it's loaded, it's possible for scripts to link based on results
from other scripts.
improving scripting

- app.help
- default text for the script box explaining app.help
- script updates to clean up the variables available from the main
window
