D language layer

This simple layer adds support for the D language.
It adds d-mode as well as integrating it with auto-completion and syntax-checking.
To use this configuration layer, add it to your ~/.spacemacs. You will need to
add d to the existing dotspacemacs-configuration-layers list in this
file.
To enable smart D completion, you need to install DCD. Here are installation
instructions. After successfully built DCD, you need to copy the binary
dcd-server and dcd-client in bin/ directory to somewhere in your $PATH e.g.
/usr/local/bin on Linux.
