Add "SSD emulation" property to IDE, SATA, and SCSI drives

Browse Source 
When enabled, the "SSD emulation" feature exposes drives as
solid-state (rather than rotational) by enabling the new `ssd`
qm.conf flag [1] on the drives, which in turn sets QEMU's
`rotation_rate` property [2, 3] on the underlying devices.

This change also moves the "Discard" option out of the advanced
section and promotes it to the top of the dialog box, as proposed
by Thomas Lamprecht [4].
