Remove terminal color specification
Remove terminal color specification

There's no need to use specify terminal color to 16, because this is the
default value. Although, in the past, this setting seemed to be required
in order for me to get colors to work properly. Thus, a reminder to self
was added in its place.

Also, the Theme & Colors section was moved up in the file to a more
logical place.

Finally, some other minor modifications were made, in order to maintain
the same style through the whole file.
