Add option to rewrite sway/window title
Rewrites window title according to config option "rewrite". "rewrite" is an object where keys are regular expressions and values are rewrite rules if the expression matches. Rules may contain references to captures of the expression. Regex and replacement follow ECMA-script rules. If no regex matches, the title is left unchanged. example: "sway/window": { "rewrite": { "(.*) - Mozilla Firefox": " $1", "(.*) - zsh": " $1", } }
