Dashboard Enhancements

KVincent

1. Currently with the dashboard editor we can change background color for cards. If would be nice if we could have the same flexibility for the text color on the card as well.
2. Would also be nice if we could add a custom dashboard background theme. This would allow us to upload a branded background that would be more pleasant on the eyes than the standard gray or white.
3. Allow us to embed a summary number in a text section. The goal of this would basically allow us to write a report with the information constantly coming in. The goal for me would basically make my dashboard look like a news article that our team can reference.
