[Cin] Updated AppImage's and Manuals

[Andrea paz]

#MatN
How stupid I am! I thought I downloaded the multibit appimage and not
the line above. However even the multibit version gives me an error:

/home/paz/Desktop/CinGG-20210731-multibit.AppImage: error while
loading shared libraries: libjbig.so.0: cannot open shared object
file: No such file or directory

I don't actually have these libraries. I have the jbigkit package that
provides the libraries:
usr/lib/libjbig.a
usr/lib/libjbig85.a

The x86_64 version, on the other hand, starts without any problems.


@Andrew
Any indications on how I should put randrik14 patches? All together
with --whitespace=fix? Other?
