Bugfix to monitor_instances calculation. All identities are now included in the monitor_instance_for(Provider) call
On behalf of amercer: Add more specific notification error messages to the UI
Created a new task 'add_fixed_ip' to ensure instances are active before receiving IP addresses
Move periodic_task decorators out in place of normal task decorators, call periodic tasks from settings/__init__.py, remove add_fixed_ip from instance service
Fixed task-naming problem with periodicTasks
