Gnats 4194: Edit Account Dialog: In "Vol" mode, no series data shown for volume-only Slots (e.g. Storage).

On 1-26-2007, a cleaned up mechanism to translate the SlotQtDlg's "Flow/Vol" toggle to Primary/Alt Units for a particular Slot was checked into PreRel. This involved an incomplete implementation of the following method. (The implementation in 4.9 builds had the problem too).

bool SlotGUIUtils::supportsAltUnits (const Slot*)

This method just took into account whether the given Slot was on an Account (or an AcctSlotSum object), and neglected to check that the Slot actually had Alt units defined. So, for the Storage Account Storage Slot (which supports only Volume units) (for example), this method was returning 'true'.

The fix is being checked into 4.9 Builds and 4.8.5+ Prerel.
