reconstructPar to decompose and reconstruct lagrangian FieldField
data.

- make centrally available via #include "addOverwriteOption.H"

- to match coding guidelines

- ensure that the standard options (eg, from timeSelector) also have
  some usage information

- markup codingStyleGuide.org examples so they actually indent correctly

- use 'Info<<' as per codingStyleGuide instead of 'Info <<'

- also drop various unused time options from src/OpenFOAM/include

- objectRegistry gets a rename() that also adjusts the dbDir
- cloud reworked to use static variables subInstance and defaultName.
  This avoids writing "lagrangian" everywhere

string fixes
- avoid masking of std::string::replace in string.H
- avoid old strstream in PV3FoamReader

- can use 'XX.empty()' instead of 'XX.size() == 0', 'XX.size() < 1' or
  'XX.size() <= 0' or for simpler coding.
  It also has the same number of characters as '!XX.size()' and /might/ be
  more readable

- many size checking had 'XX.size() > 0', 'XX.size() != 0', or 'XX.size() >= 1'
  when a simple 'XX.size()' suffices

- 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
