0c168c43fa ENH: improve startup time for foamToEnsight conversion (issue #240).
Old code:
    Found 10990 time steps
    Search for moving mesh ... no moving mesh detected.
    Startup in 329.09 s

Updated:
    Found 10990 time steps
    Search for moving mesh ... no moving mesh detected.
    Startup in 1.6 s

- Cause was checking "polyMesh/points" via an IOobject.
  Short-circuit with a check for a polyMesh/ directory first.

  Limit the check to the master-node as well to further reduce
  load on the file-system.

------------------------------

ENH: improve per-step conversion times for foamToEnsight.

Old code:
    Converting 11001 time steps
    Time [0] = 0       Wrote in 1.53 s
    Time [1] = 1       Wrote in 1.52 s
    ...
    Time [100] = 100   Elapsed time 205.35 s

Updated:
    Converting 11001 time steps
    Time [0] = 0       Wrote in 1.4 s
    Time [1] = 1       Wrote in 0.07 s
    ...
    Time [100] = 100   Elapsed time 42.4 s

- Speedup by hashing test results from the first conversion step
  instead of checking each time.

  Check data on all nodes to avoid problems with incomplete writes.

------------------------------

BUG: moving mesh detection failed for foamToEnsightParts

- adjusted to agree with updated foamToEnsight

------------------------------

Note:

- foamToEnsightParts (serial) still has about twice the throughput of
  foamToEnsight.

1452cc0827 BUG: ensight writers not catching special reserved characters (fixes #122)
- most notably the '%' which is used as a separator in places
  caused problems.

EHN: only use valid ensight file/variable names for writers

- fixed:   foamToEnsightParts, ensightSurfaceWriter
- pending: foamToEnsight

BUG: no geometry written for foamToEnsightParts with moving mesh (fixes #142)

- an incorrect path was causing the issue

e424059208 ENH: glboal file handling: initial commit
Moved file path handling to regIOobject and made it type specific so
now every object can have its own rules. Examples:
- faceZones are now processor local (and don't search up anymore)
- timeStampMaster is now no longer hardcoded inside IOdictionary
  (e.g. uniformDimensionedFields support it as well)
- the distributedTriSurfaceMesh is properly processor-local; no need
  for fileModificationChecking manipulation.

72362de6b1 foamToEnsight* fixes and tweaks
foamToEnsight:
    - add -noPatches option
    - had incorrect part# when the internalMesh was not output
    - case file is always ascii

foamToEnsightParts:
    - fixed field selection bug,
      no fields were selected when a single time-step was selected
