Changing and fixing some stuff

- QHash is better to use than QMap in MemoryManager: faster lookups, able to reserve memory in advance
- Also: reserve memory in advance for the QVector and QHash, so we don't get needles allocs for them
- No need to do cleanup for the nph manager, as it uses the generic manager for allocs, and that already gets cleaned up
