add lomanager

[calderham]

Have been using Mageia x86 KDE and just loaded x86_64 KDE and really like it. Would like to suggest removing LibreOffice packages from the install iso's and adding a "lomanager" icon on the desktop something like PCLinuxOS has done. Would free up some iso space and I think add some flexibility although don't know how much extra effort this would require. Thanks to all for Mageia, look forward to many more future releases!
