Working on ibLoginCommandHandler, others...

* I need to fix event aggregator to disallow multiple subscription to
events.
* Fixed getting the tcsx from the ibLogin event. That part seems to be
working.
* Still need to implement the actual login part that talks with the user
db and sets the login state.
* Seem to be having a problem completing the porp. Need to look at
PorpTracker.
* Some of these files were added after compiling in VS 2015 Preview.
