Bugfix for Directional Pyramid Denoising. Adding a Directional Pyramid Equalizer tool. This one serves the same function as the existing Wavelet Equalizer, but has much less artifacting; though it is a little slower to execute and has not yet been adapted for OpenMP implementation. There are also fewer levels on which the tool operates, though of course if there was a demand that could be altered. The controls are similar, though have been given separate luma and chroma controls. Each slider adjusts the factor by which a given detail band is amplified; factors larger than one increase contrast, while values smaller than one decrease contrast. The luma control alters contrast on various scales, each successive one twice as large as the previous one. The chroma control is similar, but does less since there is typically less chroma contrast on fine scales. One might use this to restore some of the color contrast lost in NR, or to remove color fringing by making the fine scale enhancement factor much less than one.

A fix for bad behavior of the GUI under the NR tools. The problem seems to be the separation of luminance and chrominance operations in all other tools besides the pyramid NR, while the latter operates simultaneously on luma and chroma data. I put all luma/chroma curves, NR, sharpening, equalizer etc. into a single grouping, which means that if any one is changed, all must be redone. This will slow down the GUI for now but I expect that the pipeline will be retooled at some point anyway.

Added a threshold slider to the impulse denoise tool. At large values it can lead to a bit of cratering, but otherwise it allows some flexibility that is useful as a precursor to the pyramid denoise filter. Small values on the slider are less impulse NR, larger values yield more NR.

Added a threshold slider to the impulse NR tool. Large values can cause cratering, but otherwise this should be a good precursor to pyramid denoising.

Reapplied Hombres patch (revision c006f93a5f) as it got lost on the way.
