[Experiment] add character info to Loadout Tab bar

[frzyc]

Describe your changes

Loadout UI doesn't really indicate which character you are on, That's why a lot of the tabs have a "character UI" in the top left above the fold. (overview, opt tab) However, this is using up valuable space that can be used to display more relevant information. I want to experiment with adding a more "static" element, rather than one baked into each page.
This PR adds a persistent character element to the loadout tab element, which shows the character and some metadata.
This is also clickable, so it can provide a editor for some char stats like level/talent
