- include bash completion for paraFoam, and provision for using
  foamEtcFile as well.

- this makes it possible to use "foamAddCompletion paraFoam" and have
  bash completions for paraFoam as well

- unknown options or missing option values now emit a shorter message
  without the entire usage. This makes it easier to identify the errors
  and is better aligned with the behaviour of GNU system tools.

  ====
     $ simpleFoam -case
     Using: OpenFOAM-plus (see www.OpenFOAM.com)
     Build: plus-01234

     Error: option '-case' requires an argument

     See 'simpleFoam -help' for usage
  ====

- provide for reduced (-help) and full (-help-full) usage information.
  In many cases the reduced usage provided sufficient and easier
  to find the information.

- make -srcDoc an alias for -doc-source

- no warnings about option aliases for future dates.

- Can be useful when investigating mesh topologies

ENH: Paraview modules.

- Update props with int, not bool (for more versatility)
- Set properties and tool-tips directly on widgets instead of buttons

- handle sourcing bashrc with a relative path (issue #383)
- handle sourcing from bash and zsh.
  Still need manual intervention when sourcing dash, sh, or ksh.
- replace grep in etc/cshrc with sed only
- logical instead of physical path for WM_PROJECT_DIR (issue #431).
  Doesn't seem to be possible for csh/tcsh.

  * Continue using physical locations when comparing directories,
    but not for the top-level FOAM_INST_DIR, WM_PROJECT_DIR.

- relocate WM_CC, WM_CXX overrides from etc/config.*/compiler
  to etc/config.*/settings to ensure that they are left untouched
  when etc/config.sh/compiler is sourced while making third-party
  packages (eg, gcc, llvm, CGAL).

- provide fallback FOAM_TUTORIALS setting in RunFunctions

STYLE: remove "~OpenFOAM" fallback as being too rare, non-obvious

- remove old VTK_CONVEX_POINT_SET code, since VTK_POLYHEDRON exists
  since several years

ENH: improve robustness of paraFoam script

- only check the relevant plugin types,
  fallback to native reader if needed/possible.

Resolves bug-report http://www.openfoam.org/mantisbt/view.php?id=2027

PV4FoamReaders: Updated to build with ParaView-5.0.0
paraFoam: Updated to load PV4FoamReaders for ParaView-5.0.0

Currently this is experimental but if it becomes clear that ParaView-4
and ParaView-5 are and will remain consistent with respect to readers
the plan is to rename

PV4 -> PV

or

PV4 -> PV45 if it is assumed that PV6 may need to be different.

Resolves bug-report http://www.openfoam.org/mantisbt/view.php?id=1803

when OpenFOAM-format case files are not located

- pass through normal paraview (double-dashed) options

- bypass the plugins logic when the --data=... option is provided.
  This allows the command 'paraFoam --data=...' to work too.

- we don't support paraview < 3.x anymore

This reverts commit c5bea524.

This reverts commit 2e1e671d.

- Also adjusted formatting of usage to match what argList generates

- mention PV3blockMeshReader in the README as well

- first version. Only uses simple hex shapes for the blocks.

- this was not agreed.

This reverts commit 41b196ff.
