bump: minor type: feature ludic.i18n: keys (phase 26). A key names what a text is for, and en.po says it in English like any other language. A key is a string with a marker byte (I18N_KEY, I18N_PLURAL), its arguments after byte 31, so the code that makes text never takes I18nState: tr(k), trf(k, a, b, c, d) and trn(k, n, a, b, c) build it, and L makes it into text where it is drawn - the language in use, else en.po (read the first time a key is asked for), else the key itself, [[key]] in a developer's build (i18n_loud). Holes take their arguments in the language's order, a key argument made first; plural keys go by each language's rule. A string with no marker takes the old English path, so a game can move over a file at a time.
