File path for the library is wrong for composer install.

I think the the more correct path for the Eyecon library is /libraries/colorpicker rather than /libraries/jquery_colorpicker.

The library author only ever calls it "colorpicker".

This is a specific issue for a project that I'm working on where we manage all dependencies with composer. We add the zip download as a custom "repository" to composer.json. I think others will hit the same issue as dependency management with composer becomes more the norm.
