Fast reactions to 2.7.8

Thanks for all the research, Geert.  I’ve done some experimentation on MacOSX and can add a bit.

It seems to be $HOME/.local/share/themes/ even in the native Aqua version of GnuCash.

~/Library/Application Support/GnuCash/config/gtk-3.0/settings.ini works for the native version of GnuCash.  If anyone besides me runs the X-Window version on MacOS, then the settings.ini file should be in ~/.config/gtk-3.0 like on Linux.

You’re certainly right that Eye-friendly-Dark-RBC isn’t the best theme, but it works on MacOS.
