Migrate Radio Buttons to TR, add a new button and refine layout

[brettforbes]

Problem

Currently the widget-graph-viz has a series of radio buttons on the left hand side. There are a few issues with this:

1. The buttons should be on top of the viz, not on the side, so as to maximise the usable screen real estate
2. We are missing a radio button for Behaviour, which should come before Sightings, except for the moment it is visible but not selectable, (needed for future feature). So the Incident buttons become (Behaviour, Sightings, Tasks, Impacts, Events) and the internal resources buttons become (User, Company)
3. The buttons are all in one group, whereas they are actually from two distinct groups (i,e, incident stuff or internal resources), ideally there is a gap between the two groups

Proposal

Actions:

1. Migrate radio buttons to TR (i.e. create messages etc.)
2. Separate buttons into two groups, Incident stuff and Internal Resources, put a gap between them, and possibly different colour themes for each group. However, only one button from either group can be selected at any time
3. Add a new button to the Incident Stuff called Behaviour, so that it would sit on top of Sightings (i.e. it is the first radio button)
