--User changes
 -Add support for adjusting xform color indices in the palette editor. Fixed palettes can now be displayed there, but they will have no color arrows as they are not editable.
 -Add support for independent dimension scaling in the EmberRender and EmberAnimate programs to bring them in line with the final render dialog Fractorium.

--Bug fixes
 -File paths with a space in them did not work in the command line programs.
 -Any Xml file in the search paths would erroneously be treated as a palette file.

--Code changes
 -Change some for loops to while loops when iterating through xforms.
 -Allow FractoriumEmberController<T>::UpdateXform() to be able to apply the action to an xform at a specific index.
 -Remove old code blocks build files that were never used.
 -Make GetPath() return empty string if no path is present in the passed in file path.
 -GetTotalXform() was always counting the final xform, even if it was unused.
