dashboard: Add submit/close hooks for custom argument editors 

These are used by ndscan, as re-serialising the entire ndscan
parameter metadata tree, which can grow to be quite extensive,
on every single Qt change event is a bit excessive (and would
probably cause a bit of lag while typing for big experiments
on low-end machines).
