New function css-color (accompanying x11-color)

I was asked if LilyPond could support choosing colors by their CSS name,
which I found a reasonable wish.

This commit makes make-x11-color-handler generic and specifies
a new function css-color. From this it would be easy to also add further
namespaces and color lists.

CSS colors are case insensitive, so this commit also provides support for
this. Incidentally, a warning is now issued when the requested color is
not defined (instead of silently falling back to black).

Only warn about missing color when necessary

Merge pull request #6 from rettinghaus/dev/urs/css-fonts

add named colors from CSS Color Module Level 4

Rename x11-color.scm to color.scm

With the previous commit adding css-color the file x11-color.scm should be
rename to the generic color.scm.

add named colors from CSS Color Module Level 4

Define function css-color (accompany x11-color)

It should be possible to specify colors using the CSS names in addition to
the X11 names.

This commit makes make-x11-color-handler generic and adds a function
css-color.
What remains to be done is (of course documenting and) filling in the remaining
~140 colors.
