Removes Noise Reduction settings from Preferences

- Noise Reduction settings removed from
  Preferences > Performance & Quality
- Performance & Quality renamed to Performance, container frame renamed
  to Threads, since it applies to more than just the NR tool.
- Localization keys removed.
- TP_RETINEX_GAINTRANSMISSION_TOOLTIP key revised, closes #3299

-PREFERENCES_DAUB_LABEL;Use Daubechies D6 wavelets instead of D4
-PREFERENCES_DAUB_TOOLTIP;The Noise Reduction and Wavelet Levels tools use a Debauchies mother wavelet. If you choose D6 instead of D4 you increase the number of orthogonal Daubechies coefficients and probably increase quality of small-scale levels. There is no memory or processing time difference between the two.
