Simplify erp5_upgrader to be possible upgrade any project just enabling the alarms that all Constraints will be called and fixed.

The alarms were renamed to cover each step of upgrader and give the possibility to call each step manually one-by-one. Also, all Scripts that the logic can be done by installing Business Template was removed.

Also added:
 - Constraints that can be used in the upgrader
 - Unit test to check different scenarios
 - Extend external method to be possible dump workflow chains to be compared with all configuration defined on Business Templates
Add Business Template with Constraints as a example of bt5 with all configuration required to upgrade
Improve code to call checkConsistency through activities if hundred of objects because loading all objects can kill the perfomance

Also, Added test to Folder.recursiveCheckConsistency method
Add ConstraintType property sheet to all constraint portal types
Improve code because is not needed call fixConsistency twice
Base.checkConsistency: s/error_list2/extra_error_list/
