--User changes

-Add a palette editor.
 -Add support for reading .ugr/.gradient/.gradients palette files.
 -Allow toggling on spinners whose minimum value is not zero.
 -Allow toggling display of image, affines and grid.
 -Add new variations: cylinder2, circlesplit, tile_log, truchet_fill, waves2_radial.

--Bug fixes
 -cpow2 was wrong.
 -Palettes with rapid changes in color would produce slightly different outputs from Apo/Chaotica. This was due to a long standing bug from flam3.
 -Use exec() on Apple and show() on all other OSes for dialog boxes.
 -Trying to render a sequence with no frames would crash.
 -Selecting multiple xforms and rotating them would produce the wrong rotation.
 -Better handling when parsing flames using different encoding, such as unicode and UTF-8.
 -Switching between SP/DP didn't reselect the selected flame in the Library tab.

--Code changes
 -Make all types concerning palettes be floats, including PaletteTableWidgetItem.
 -PaletteTableWidgetItem is no longer templated because all palettes are float.
 -Include the source colors for user created gradients.
 -Change parallel_for() calls to work with very old versions of TBB which are lingering on some systems.
 -Split conditional out of accumulation loop on the CPU for better performance.
 -Vectorize summing when doing density filter for better performance.
 -Make all usage of palettes be of type float, double is pointless.
 -Allow palettes to reside in multiple folders, while ensuring only one of each name is added.
 -Refactor some palette path searching code.
 -Make ReadFile() throw and catch an exception if the file operation fails.
 -A little extra safety in foci and foci3D with a call to Zeps().
 -Cast to (real_t) in the OpenCL string for the w variation, which was having trouble compiling on Mac.
 -Fixing missing comma between paths in InitPaletteList().
 -Move Xml and PaletteList classes into cpp to shorten build times when working on them.
 -Remove default param values for IterOpenCLKernelCreator<T>::SharedDataIndexDefines in cpp file.
 -Change more NULL to nullptr.
