Menu re-organization

The number of AROS applications included in VmwAROS is growing, so I had to partially re-organize AmiStart menus. Let's welcome the File manage and the Futilities menus, which will include file managers like Dopus and Filemaster, but also some useful tools like the Finder and the burning app FryingPan, and some inutilia like the Alarm Clock and the Simple Text Editor respectively (and others...). The next VmwAROS will come with more games and utilities as well, and I hope there will be room for some surprises too.
