- Used to semantically mark AllocationTables and AllocationEntries (e.g., which layers of the system are connected by allocation, and which system entities)
 - Add IAllocationService.addAllocationEntryType() and getAllocationEntryTypes() to register and query IAllocationTypes
 - Apply IAllocationTypes specializations to Task, Partition and Hardware architecture allocations

2) Move TaskToExecutionUnitAllocationTable and TaskWcetTable to af3.task (to avoid circular dependencies that would arise from the introduction of IAllocationType)

3) Schedule model UI
 - Use IAllocationTypes to provide unified generic UI in af3.schedule.ui
 - Remove most of the temporary hacks since allocation[.ui] is now in the build
 - TODO: Remove SystemScheduleDeploymentPropertySection once Deployment has fully been replaced by AllocationTable
