Small updates to the dashboard removing unnecessery css and making the row displaying the bubble graph bigger. Also added the functionality for the detail donut view of the # of evidence per agent

Renamed the donut script to simple-donut script and changed the dashboard to include the renamed script

Changed a bit the layout + added two visualizations to show the # of entries in the database for the RawData and Evidences respectively

Moved the reload script to reload only the visualization container instead of the whole page, that way only the visualizations are redrawn.

Added a bubble-script blade that can be included in the dashboard view and bubble.blade view, displaying the Bubble graph. That way there is no duplication of code
