Allows generating a plain text version of an issue (i.e. without colors and other terminal formatting) when storing stdout in a file. ``` tea issue --comments 1 > issue1.txt ``` `IsInteractive()` had to be moved to avoid a recursive import chain. --- In the future, it would be nice to also respect the `--output` flag. This flag is currently designed for tabular output, but we could add more supported values like `markdown` `ansi`, `plain` to it Co-authored-by: Norwin <git@nroo.de> Co-authored-by: 6543 <6543@obermui.de> Reviewed-on: https://gitea.com/gitea/tea/pulls/491 Reviewed-by: 6543 <6543@obermui.de> Reviewed-by: delvh <dev.lh@web.de>
