Refactored the `format` placeholder. New Syntaxes: - `%formatter_number_format_<number>%` - `%formatter_number_format_<locale>:<format>%` Both `<locale>` and `<format>` can be ommited to use the default value. `text_join` syntax has changed to allow defining own target character(s): - `%formatter_text_join_<target>_<replacement>_<text>%`
