fixed many tests to run using python 3
#287 Py3 fix that was breaking all graphs
Fixes #284 by removing the too broad BaseException. It now checks if the file exists.  This will throw an error page if the user has the DB open in another program.
Corrected the name on auto_vacuum mode
#185 Major: Added Fatal Errors list checking for specific rules.  I need more detailed specs for validation rules.
Rename adsm.exe to adsm_simulation.exe. Modify gitignore to work with new build chain.
