Add Color and Change UI Layout

[KeithBallard]

I made a few modifications to the UI layout so that each column has its own label, the current directory/search query has its own row, and added color. Example current directory: Example search query:

I have tested it on Windows, but have not had the chance to play with it on Linux. The reason for adding the directory column label is that I find it easier to know where the cursor is. I understand that the UI had feedback indicating the location, but as a new user, consistent indicators is much appreciated. As for the color...it is just more fun!...and arguably easier to mentally parse quickly.
