Agreed that ctrl-click of an already selected item should un-select it 
(in the multi-select case).

The reason for having to ctrl-click an item when none are selected to do 
multi-selecting is due to the tupane paradigm.  Say you normal click an 
item from the list.  You get the details page that slides out and 
obstructs the right pane actions - the actions that were added last 
sprint and can affect multiple items (e.g. for the systems page, Remove 
Systems).  Then, if you keep selecting items you can never perform 
actions on them unless you manually click the 'close' button.  I could 
potentially see an argument for:

Nothing Selected:
Click an item - tupane details slide out
ctrl+click another item - tupane details slide back in and the user is 
left in the 'mutli-select' state

Nothing Selected:
ctrl+click item when none selected provides current behaviour
