[oslc-core] [oslc-cm] Issue on redundant inverse predicates

[Steve K Speicher]

Per resolution to mark these terms deprecated, I went ahead and created 
new section to hold all deprecated terms [1] and marked them as such in 
the vocabulary document [2].  I even overachieved and closed an older 
issue that was marked deferred around deprecating dcterms:type usage [3].
