CMake: Add support for building and installing .mo files
Introduce support for building translation domain-specific templates, merging them with the translations, and building a language-specific .mo file. The invocation of xgettext is done in the project source directory, not in the current source directory, and all paths are made relative to the project root, in order to have clean templates. This only supports the C++ source code for now, it unfortunately does not handle the shell scripts of deselect yet.
