* add anki_i18n and locale_config crates to launcher
* add launcher.ftl
* add tr to state
* replace most hardcoded strings with translations
* add support for `launcher` rustcfg to trim translations
* use marker structs to denote type of translations
* move underscores into generated code
* Update cargo-license, which may fix the license order issue (dae)
* Add number-truncation before backend translation
* Round instead of truncate (conform to testcases)
* Add test-case for plural rounding-to-one corner-case
* Move rounding into generated translation code
* Change unit test to test generated function
* Round any number in generation, ignore (int vs float)
(it seems that that type distinction is frequently inaccurate)
* Update formatting
