cmake: generate the shell/perl/python scripts and templates, translations
Implement the placeholder substitution to generate scripted Porcelain commands, e.g. git-request-pull out of git-request-pull.sh Generate shell/perl/python scripts and template using CMake instead of using sed like the build procedure in the Makefile does. The text translations are only build if `msgfmt` is found in your path. NOTE: The scripts and templates are generated during configuration.
