Add stat buff summary to Inspect Equipment option

[SlappedWithSilence]

The user will have to manually calculate things like total armor, total dmg, and most importantly, total resistance. Add a simple display of stats either to the Equipment summary or to a new menu.

Note that the inventory does not currently deffer inspection to the specific Inspect[object]Event classes. Swapping the hard-coded inspection logic to the specific inspection logic defined in those events will simplify the code and improve maintainability.
