New fuels are iso/n-propanol and urea.  Although urea is a bit dodgy, but that's
all of the properties Ive found so far.

I've also added a variation of temperature instead of constant temperature for
some injector-classes so Im sending you the new version of the dieselFoam
tutorial also.

- moved findStrings from stringList to new stringListOps
  (helps reduce the influence on dependencies)
- findStrings can also do partial matches

- the improved side-effect of enabling -zeroTimea alters default selection
  behaviour and -latestTime selection behaviour for utilities in which
  accidentally using the 0/ directory can cause damage (eg, reconstructPar)
- can combine -time ranges and -latestTime

- allow banner to be disabled (for easier parsing of utils output)
- amalgamate distributed/non-distributed code chunks

  - can now use dictionary substitutions and regular expressions in
    system/fvSolution

  - foamUpgradeFvSolution application to convert system/fvSolution
    (with -test option)

motion solver syntax left as-is.
