runtime(colors): color names in the v:colornames dict should be lower cased

Browse Source 
Vim will lookup color names from the v:colornames dictionary by its
lower case color name. So when sourcing the v:colornames dictionary,
make sure to convert upper case color names to lower case.

Also, while at it, mention in the documentation, that the dictionary
should contain lower case names only.
