Added load order dependency with hibernate, gorm

Added load order dependency with hibernate and gorm to ensure the methods they add to the domain classes are already present by the time activiti loads, in case a task fired at start-up will need them.
This can happen if we have a timer-triggered task with a timer that is overdue when the plug-in starts (i.e. because the application was down when it was programmed to fire). As soon as the plugin loads, the overdue timer is triggered and the task/process attached to it fire. If the task happens to call a method that uses a GORM-autogenerated method (`findBy*`, etc.) and the gorm/hibernate plugins haven't loaded yet, the call to the method will fail.
