- fix 'forAll (' -> 'forAll(' format (again)

uniformDimensionedVectorField.

location for the specification is the same as that for the pd level.

- change system/controlDict to use functions {..} instead of functions (..);
  * This is internally more efficient
- fixed formatting of system/controlDict functions entry

- pedantic change: use 'return 0' instead of 'return(0)' in the applications,
  since return is a C/C++ keyword, not a function.

Changed formatting of interDyMFoam
