Prefer string variant for source-list-line-color config option (#2676)

Browse Source 
The string variant is more powerful and can be passed
directly to "echo -e" / "printf" and friends.

Remove the mention of the integer variant from the default config. This
makes the option appear more consistent with other color options.
The user shouldn't care about the historic differences.
