When required, also adjusted to use XXXApp.C for the source name.
Adjusted some names in preparation for merge with master.

The call to foamCleanPath from etc/{bashrc,cshrc} passes all the wildcards
together as a single argument - causing nothing to be cleaned.  Now split
the args on whitespace. Also added more IFS hacking to reduce forking.

This is useful when the application has the same name as a class. For example,
polyDualMeshApp.C implements the polyDualMesh application using the
polyDualMesh class. Thus polyDualMeshApp_8C.html documents the app, whereas
polyDualMesh_8C.html is the annotated source code for the class itself.

Sorted the boundary condition list to ease tracking in the future.

Added replace() method to DLListBase.
Modified the dictionary merge code to avoid scrambling the order, but left the old version active for now.

Lookup liquidProperties in thermophysicalProperties (avoid conflict with
gas-phase).
Changed liquidFuelComponents to liquidComponents.
Updated dieselFoam tutorial to reflect the changes

Added edgeDirection methods for face/triFace.
Added extra constructors for converting faces to triFaces.
The collapse() method now returns the new face size and can be used to check
if the collapse face is valid.

noticed and to make the engine geometry optional
