Purpose of change

The current brick wall sprites are a mixed bag, having quite a flat, dull look. The red bricks are using an intense Christmas red
color, while the adobe brick uses a very pale yellow. For some reason the bricks themselves do not tile either, but rather uses a
sort of self contained look.

Describe the solution

This change aims improve the look of t_brick_wall and t_adobe_brick_wall multi tile sprites.
The new sprites seamlessly tile, includes some highlights and brick color differences to give them a bit more natural look.
This change also omits the bg property from said tiles, as I could not find a use for it. When deconstructed, a new tile is created in place. Please correct me if I'm wrong here.

Describe alternatives you've considered

Including an update for the "t_adobe_brick_wall_halfway", but decided against it. The reasoning for this is part that the halfway built red brick walls is a multi tile sprite which was not in need of updating while the adobe halfway is a single tile, which uses a transparent background, requiring then to include an override of the bg tile bg_dirt. Which I didn't intend to update.
Lastly, the current adobe halfway tile still work pretty good with the updated sprites, hence my decision to omit it from this change.
