Various improvements and additions. I couldn't be bothered to untangle this, so here it goes: * Log colors depending on loglevel * Simplified Filelogger * Remove description=None from basetask * create_list creates task list from argument now * Task rollback feature: If a task fails, the tasklist calls rollback() on the completed tasks in reverse order * Added TaskException to common.exceptions as a base to extend from * Added TriggerRollback task to common.tasks for development purposes * An EBS volume for bootstrapping is now created and attached to the instance (including rollback actions) * EC2 Connect task now depends on host.GetInfo 2013-06-24 23:12:39 +02:00			`from base import Task`
			`import phases`
