1.0.0.2 12/05/2016

--User changes
 -Add many tooltips to help clarify functionality.
 -Select multiple flames in library for del/move. Still only one allowed to be set as the current.
 -Show checkbox for current flame. Remember this is not necessarily what's selected.
 -User can now drag a square to select xforms, which keeps in sync with checkboxes.
 -Remove --nframes from command line. Replace with new params: --loopframes, --interpframes, --interploops.
 -Add two new options to EmberGenome: --cwloops --cwinterploops to specify whether rotation should go clockwise instead of the default counter clockwise.
 -Add these to Fractorium as checkboxes.
 -Apply All now also works for toggling animate flag on xforms.
 -Options dialog now allows user to set whether double click toggles spinners, or right click does.

--Bug fixes
 -Selecting final and non-final xforms, and then dragging the non-final did not drag the final with it.
 -Selecting all xforms when a final was present, then deleting crashed the program.
 -Remove support for ppm files in the command line programs, it's an outdated format.
 -Switching between SP and DP kept reapplying the palette adjustments.

--Code changes
 -Move build system to Visual Studio 2015 and Qt 5.6.
 -SSE used during addition of points to the histogram.
 -Remove last remnants of old flam3 C code and replace with C++.
 -Remove unused code involving tbb::task_group.
 -Make settings object a global shared_ptr singleton, so it doesn't have to be passed around.
