Improved support of KolibriOS:

CD-ROM (iso), Disk, Internet and Audio are working now.
Also added forced LiveCD booting (because release named latest-iso, not latest-img).
Did some tweaks with '-machine' and '-cpu'. Now these VMs will run with 'qemu32' processor since KolibriOS throw an MTRR error (I didnt get how to fix it by any other way).
