BUG: Failure in medium level tests (standard tutorials till completion)

1. /export/muttley2/prashant/BACKUP/tutorials_ofdev-OpenCFD.develop_11Dec/compressible/rhoSimpleFoam/angledDuctExplicitFixedCoeff (corresponding test in OF231 succeed:/home/alex2/prashant/OpenFOAM/OpenFOAM-2.3.1/tutorials/compressible/rhoSimpleFoam/angledDuctExplicitFixedCoeff/)

2. All foamyHexMesh cases

3. Fix the case incompressible/simpleFoam/airFoil2D, doesn't contain 'boundary' file.

4. Fix the Allrun script mesh/foamyHexMesh/simpleShapes/Allrun (searches inside constant/triSurface twice!) e.g. /export/muttley2/prashant/BACKUP/tutorials_ofdev-OpenCFD.develop_11Dec/mesh/foamyHexMesh/simpleShapes/log.surfaceBooleanFeatures

5. combustion/fireFoam/les/flameSpreadWaterSuppressionPanel
