v0.4-alpha

Updated console to use named pipes, for stability.
Can close and quit repeatedly without issue now.
UI updates (still a bit jank, but usable).
New settings format (JSON).
Current config is automatically saved when closing the UI which avoids desync issues when you re-open the UI.
Preliminary work for parameter monitoring. Can specify a list of decimal parameters to check in the UI, and every time you call _lum_dbg_checkvars it will log if any have changed. Unfortunately I haven't (yet) found a way to reliably check all changes. I thought once per frame would work, but they could change multiple times per frame and I would rather require manual polling than mislead people into thinking we're capturing everything
