noise profile: move from presets to custom lookup table + combobox.

this comes with a couple of advantages:
- can now select radius/strength independent of noise parameters
- startup times are faster (less sql)
- more verbatim user feedback (combo says: ``interpolated from..'')
- we can now do an auto-setting that will intelligently
  transfer to other images when copy/pasted and interpolate
  to the right iso each time (not included in this patch yet)

also
- library injected presets from gen-profile script still work
