Add. new version.h, which included now the build version.
Adapted build.sh - to extract the build version from versioh.h and sends it to translation script.
The highest version of bash shipped by vanilla macOS is 3.2, and it will
stay like that for the foreseeable future (bash being removed as default
in 10.15 is a strong indicator for that).
The build.sh script used Bash 4.x syntax for enumerating available
translations - this patch dials back the clock to Bash 3.x making things
work again on macOS and (hopefully) still maintaining functionality on
other platforms that use a newer version of bash.
