- improves the chances of tracking who built OpenFOAM, where, etc

ENH: make it easier to parse version/build from OpenFOAM -help output

- For example,
    foamListTimes -help | awk '{ if (/^Using:/) print $2}'
    foamListTimes -help | awk '{ if (/^Build:/) print $2}'

This reverts commit 2e1e671d.

- platforms/WM_OPTIONS/lib
      old: lib/WM_OPTIONS

- platforms/WM_OPTIONS/bin
      old: bin/WM_OPTIONS
      old: applications/bin/WM_OPTIONS

A runtime environment nows needs
    - bin/
    - etc/
    - platforms/

- not required since the addition of the '-f' option

- To-do:
      wmake/rules/General/bison
      wmake/rules/General/btyacc
      wmake/rules/General/btyacc++
      wmake/rules/General/byacc
      wmake/rules/General/moc
      wmake/rules/General/yacc

  but these files have <TAB>

COMP: Fedore13 has linkage with --no-add-needed as default. This disallows indirectly loaded libraries.

wmakeFindEmptyMake:
- Find 'Make/' directories without 'files' or 'options'.
  These typically correspond to (partially) removed applications.

BUG: syntax error in settings.sh

- main mplib rules located in GENERAL_RULES with specializations
  (if any) under RULES. Modest change in a few options files, but
  cleans up the rules directories.

  previously in options:
      include $(RULES)/mplib$(WM_MPLIB)

  now in options:
      sinclude $(GENERAL_RULES)/mplib$(WM_MPLIB)
      sinclude $(RULES)/mplib$(WM_MPLIB)

  For GNU make it would be permissible to write both in a single line.

ATTENTION: cpp now needs '-traditional-cpp' for single-line output

- adds more DWIM (do what I mean) intelligence to wmake

ENH: use ~/.OpenFOAM/.wmake instead of ~/.wmakeScheduler for the lock dir

- keeps more of the OpenFOAM bits together

- otherwise /lib/cpp may need a different library binding than
  currently available and results in this type of error:

  /usr/lib64/gcc/x86_64-suse-linux/4.4/cc1:
  /data/app/OpenFOAM/ThirdParty-1.6.x/platforms/linux64/gcc-4.3.3/lib64/libstdc++.so.6:
  version `GLIBCXX_3.4.11' not found (required by
  /usr/lib64/libppl_c.so.2)

ENH: remove unused flex++ rule for SiCortex that was identical to the
general one anyhow.

ENH: generalize rule for X11

ENH: Avoid move in flex/flex++ rule.

- more consistent script names
- remove '-help' option from internal scripts
