Also renamed variables to match the name change when possible.

+ Implement some stubbed methods in smtk::operation classes
  and test them.
+ Add C++11 callbacks for listening to operator events (all
  of them, not just individual operators like the model-
  operator callbacks did).
+ Add behaviors to the ParaView extensions that do client-
  server communication of selections.
+ Add pqSMTKResourceManager proxy that gets created by
  pqSMTKResourceManagerBehavior upon plugin startup.
  All the selection management stuff in the behavior should
  eventually be moved into the proxy class.
+ Add pqSMTKResource proxy that registers itself with
  the VTK/PV-wrapping of SMTK's resource manager.
+ Fix documentation and add stubs for documenting the
  `smtk/extension` directory.
+ Add Qt extension classes that expose the new
  descriptive phrase classes in `smtk/view`.
+ Use the new qtDescriptivePhraseModel in a panel
  to show resources in ParaView as a behavior.
+ Eliminate client-server duality.
  For now, we work only with PV's built-in server,
  not separate client+server processes.
  This means that there is no need for operator
  forwarding, separate resources on the client and server,
  problems synchronizing the client-only attribute panels
  with models that are modified only on the server, etc.

Some instances were missed here due to those not being compiled with the
build settings I used; they can be picked out a lot easier now though.

This allows the robot to enforce formatting and fix formatting issues
automatically.

Qt4 and Qt5 can conflict when using the module in the include path.

Made all the guards to be consistant in the extension/qt directory - __smtk_extenstion_xxxx_h

Moved all qt classes into new namespace

This patch includes the following changes:

+ Eliminate a shiboken warning (do not wrap cJSON methods).
+ Fix a stupid mistake causing a warning in ExportJSON.
+ A scripted rename. Ran this command:

      find smtk/bridge -type f -exec vim -S /path/to/vscr {} \;

  where `vscr` contained

      %s/SMTKSessionExodusExports/Exports/g
      %s/SMTKSessionExodus/smtkExodusSession/g
      %s/SMTKSESSIONEXODUS_EXPORT/SMTKEXODUSSESSION_EXPORT/g
      %s/discreteSessionExports/Exports/g
      %s/SMTKRemoteExports/Exports/g
      %s/SMTKRemote/smtkRemoteSession/g
      %s/SMTKREMOTE_EXPORT/SMTKREMOTESESSION_EXPORT/g
      wq
+ Another scripted rename:

      find smtk/extension -type f -exec vim -S /path/to/vscr {} \;

  where `vscr` is a vim script containing:

      %s/QtSMTKExports.h/Exports.h/g
      %s/QTSMTK_EXPORT/SMTKQTEXT_EXPORT/g
      %s/vtkSMTKModule/smtkVTKExtModule/g
      %s/vtkSMTKExports/smtkVTKExtExports/g
      %s/VTKSMTK_EXPORT/SMTKVTKEXT_EXPORT/g
      %s/vtkSMTK/smtkVTKExt/g
      wq

+ Add VTK-style Python wrapping to the classes in vtkSMTKExt
  (which cannot be named smtkVTKExt because of VTK's build system).
  This should close #97.
+ Fixes to get things building again.
