ATTENTION: cpp now needs '-traditional-cpp' for single-line output

- (have been disabled for more than 1 year)

- adds more DWIM (do what I mean) intelligence to wmake

ENH: use ~/.OpenFOAM/.wmake instead of ~/.wmakeScheduler for the lock dir

- keeps more of the OpenFOAM bits together

- use enhanced Switch constructor and the new valid() method to
  avoid potential pitfalls of using Switch::switchType directly.

- add operator=(const switchType) to avoid this type of problem:

      Switch sw;
      sw = Switch::asEnum("foo", true);
      if (sw) ...  // evaluated incorrectly

- add constructor Switch(const switchType) for convenience

- add valid() method to avoid using the switchType directly

We filter them out now when constructing the adjacency structure.

non constraint patchFields on constraint patch types (all fields)

field directly.

Renaming Ftot to accelTot to remind that the functions return
accelerations.

calcCoupled/calcNonCoupled arguments and call.

before:
    - 'new' prefixed to camel-cased class name: eg, someClass -> newSomeClass
    - 'New' prefixed to templated class name:   eg, TmplClass -> NewTmplClass
    - 'New' suffixed to class name:             eg, someClass -> someClassNew

after:
    - consistent 'New' suffixed to class name, no change of case
          eg, someClass -> someClassNew
          eg, TmplClass -> TmplClassNew

- accept some violations of the coding guidelines though
- perhaps adding a style exception would be simpler.
