Object cleanup and relocating code to clr-host
Less leaks & less explicit collection usage in the driver. GCHandle seems like a better fit. Also fixes a freeing to early issue that Salsa has when using delegates: https://github.com/tim-m89/Salsa/blob/master/Foreign/Salsa/Core.hs#L424-L428 Looks like there's other leaks still remaining though.
