What changed in 0.15.0

Script intervals accept millisecond precision. The clock gets an ISO 8601 calendar and timezone-tooltip-format. The layer-shell namespace now follows the bar's name option, so compositors can apply layer rules per bar. Multiple batteries are handled better; dwl/tags gets an empty-tag option.
