Migrate0900

Migrate from release 0.8.14 to 0.9.0

The release 0.9.0 is not backward compatible since it uses a new database schema. The different steps of the migration are the following:

   > cd scripts
   > ./run dump ../models/_db_pro.py
   > ./run mysql ../models/_db_pro.py dbschema_0900.sql
   > ./run mysql ../models/_db_pro.py graphs_0900.sql
   > ./run loop ../models/_db_pro.py fix_country_0900.py
   > ./run loop ../models/_db_pro.py fix_origin_0900.py
   > ./run loop ../models/_db_pro.py fix_publisher_0900.py
   > cd ../models
   > mv ux0_preferences.py.off ux0_preferences.py
   > mv ux0_authors_roles.py.off ux0_authors_roles.py

Launch web2py
Run the application
Rename the files ux0_preferences, ux0_authors_roles to *.py.off
Check the list of publisher against doublon, empty names, etc.
