--User changes

-Highlight power is now on by default.
 -Allow for adjustments on the Flame tab to apply to all open flames in the file.
 -Add two new buttons to the color tab to randomize and toggle the xform color indices.
 -Remove the --strip option from EmberGenome. It was useless and was likely just a carry over from flam3 during its early debugging stages when testing strips.
 -Make randoms in EmberGenome have default dimensions of 1920 x 1080.
 -Prevent --inter and --rotate in EmberGenome from rotating backward before the first flame since it doesn't really make sense.
 -Ensure every loaded flame has at least one xform in it.
 -Change dark.qss to hide dotted selection outline around checkboxes. Users must reload it to take effect.

--Bug fixes
 -The saving of last.flame during editing was appending the file when it should have been replacing.
 -It was impossible for EmberGenome to create a random flame. It can now be done by specifying no arguments: EmberGenome.exe
 -Crossing in EmberGenome was not logging the performed actions to the edit Xml tag.
 -Apply sub batch size and fuse count to template files used on the command line.
 -Use new default filter types with template files.

--Code changes
 -Use cerr in SheepTools instead of cout.
 -Set m_SubBatchSize and m_FuseCount to default values in Ember::Clear().
 -Clean up some command line options text formatting.
