Bug fixes

In the reproducible documents collection:

• Cross-platform (Linux/Mac) solution in book/jsg/flat/*/SConstruct

• Fixed program links in book/gee/ajt and book/gee/hlx
• High-resolution figures in book/gee/hlx

In documentation:

• Update of html/txt/spec documentation and man pages triggered by changes in programs or examples through dependence on use.py
• Show y and n for boolean parameters in F90 programs, instead of .true./.false.
• Show y and n for boolean params in some Python programs instead of True/False (fix for some cases in which existing mechanism did not work)

In APIs:

• Appropriate flags for compilation on OpenSolaris
• Fixed memory leak in getpar.c
