Initial commit: new filter - SV Lowpass
Adds a state-variant 4-pole lowpass filter into LMMS, which I swiped from Nekobee and slightly adapted to work in LMMS
It is possible that with some adjustments a highpass version could also be produced (will have to look into that)
It sounds really cool, kind of like the moog filter but has more character, esp. on high Q values
Correct samplerate-agnostic behaviour
Add more filters!

New filters: SV Lowpass, SV Bandpass, SV Highpass, DoubleMoog
LMMS Memory Manager
Fix 64 bit, increase mm usage
Fixes
More fixes
Add dedicated manager for noteplayhandles
This caches and reuses nph's independently of the generic memory manager.
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
