[Cin] March end of month new releases now available

[Andrea paz]

>From line 6 of the new bld_appimage.sh it says:

60 # Use own version of linuxdeploy, makeappimage. This should be in
61 # subdirectory tools, if not, go to tools/makeappimagetool and do bld.sh
62 # there. That will place the makeappimage executable in tools, and
63 # then delete all other generated files (except the small log). The tools
64 # directory is not cleared with "make clean" or "autogen.sh clean"

Maybe you should correct "subdirectory tools" in "subdirectory
cinelerra-5.1"? If you confirm it I'll fix the manual by putting the
"our" linuxdeploy (i.e. "makeappimagetool", if I understand correctly)
instead of the git one.
