--User changes

-Remove the option --intpalette to format the palette in the xml as ints. If they are not hex formatted, then they should always be float. This option was pointless.
 -Cleanup some options text for the command line programs.
 -Allow for dragging around flames in the library tab. This is useful for setting up the order of an animation.
 -Make the opening of large files in Fractorium much more efficient when not-appending.
 -Make the opening of large files in all EmberRender and EmberAnimate more efficient.
 -Better error reporting when opening files.

--Bug fixes
 -Get rid of leftover artifacts that would appear on preview thumbnails when either switching SP/DP or re-rendering previews.
 -Filename extension was not being appended on Linux when saving as Xml, thus making it impossible to drag that file back in becase drop is filtered on extension.

--Code changes
 -Move GCC compiler spec to C++14. Building with 5.3 now on linux.
 -Use inline member data initializers.
 -Make a #define for static for use in Utils.h to make things a little cleaner.
 -Make various functions able to take arbitrary collections as their parameters rather than just vectors.
 -Make library collection a list rather than vector. This alleviates the need to re-sync pointers whenever the collection changes.
 -Subclass QTreeWidget for the library tree. Two new files added for this.
 -Remove all usage of #ifdef ROW_ONLY_DE in DEOpenCLKernelCreator, it was never used.
 -Add move constructor and assignment operator to EmberFile.
 -Add the ability to use a pointer to outside memory in the renderer for the vector of Ember<T>.
 -Make a lot more functions const where they should be.
