Disable deletion of historical events when deleting a device

[jstevens]

Deleting multiple devices can cause gridlock as multiple processes are spawned to delete historical events. Per EAD this is being disabled in 2.2 and we'll revisit it later.

When selecting one (or more?) devices from the device list and using the remove devices menu item the dialog still has the 'Delete historical events...' option. Looks like there is more than one remove devices dialog?
