- old-style (left untouched for now): app, lib, run, sol, tut, util - new-style: foamApps, foamLib, foamRun, foamSol, foamTut, foamUtils - additional aliases: userApps, whichFoam NB: ideally we'd have 'foamSrc' instead of 'src'. Do we really need 'foamsrc' and 'foamfv' anyhow?
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.
