- switch border colors to Xft

- merge border/menu color structures/functions since they now both use Xft
- switch xu_xorcolor to operating on XftColor instead of just
  XRenderColor (basically adding pixel)
- if color name allocation fails, revert back to default (this, along
  with font validation should occur during config parse, but we don't
  have screens setup yet - likely to change at some point)
