v1.15

Changes

• Change to alert badge coloring. A condition alert that is on, or a condition alert that has not yet been acked and ack_required was set, or an event alert that has not yet been acked, will be colored based on priority. The default is blue for low, orange for medium and red for high. Otherwise the badge will be grey. Colors may be customized.
• Add new config options, low_priority_color, medium_priority_color, high_priority_color, and off_color to customize alert badge colors.
• Old unacked alerts that have ack_required will persist in the Alert Overview card. This means include_old_unacked is probably obsolete now.
• Fix bug in rendering of data dictionary in yaml display.
