- could also move to utilities/miscellaneous

- the dictionary compare contents might be useful enough to move
  into dictionary code.

- usage example (w/o -rewrite):

      for i in $(find -name fvSolution)
      do
          fvSolutionCombine -case "${i%/system/fvSolution}"
      done

- this would be an argument for providing default values at the top-level
  compressible/incompressible turbulenceModel

- avoids raw values sprinkled about the code
  eg, 'defaultKappa_'  vs. '0.41'

- got hit by spacing error and it took too long to pinpoint the problem:

  #include "XXX"   <- okay
  # include "XXX"  <- wrong!

- compile into linux64Gcc44, linuxGcc44 to avoid clashes during testing
- continue to use gmp-4.2.4 since gmp-4.3.x might be miscompiled with
  a system gcc-4.3.2

- partial revert for
  commit 9557f2cb

Removed network tests.

- also gives better isolation between scripts

- this stop problems caused by a "-case .." specification

  Previously  args.globalCaseName() + ".Ext"  resulted in silly names
  eg, "...png", or "surface-...stl"
