Webconfig: Pass colorscheme in one json request

This used to pass each color in a separate url-encoded request, which is
just wasteful.

Also it passed separate parameters for modifiers like bold and
underlined, but never gave them actual values. Instead the color is
passed as one string.

So we just use json, and then iterate over it server-side.
