Different Selection and Flash colours

[TheFletch]

Dashboards currently support defining 1 selection colour which is used by the selection tools in the map as well as by the flash action that can be defined in widgets like the list.

The ability to define a different flash colour would help in dashboards where the user selects features in a map, this map selection action filters records in a list, records selected in this list flash the location of the record in the map.

But the same selection colour being used makes the flash action less visible
