Fix d-mode

[d-torrance]

I recently noticed that D-mode.el exists (and apparently has for a very long time). However, it's not installed and the corresponding lines in M2-init.el are commented out by default.

Is there a reason it's not installed? There's the possibility of a name clash, e.g., with d-mode, especially on systems where filenames are case insensitive. Perhaps a rename to something like M2-D-mode.el?

Yes, I haven't used it in years. (I just activate M2-mode on *.d files.) Renaming it and providing it would be good. Checking that it behaves well would also be good. (Notice that the file is now in a submodule.)

The distributed M2 packages don't carry .d/dd files or the scc1 compiler, so there's no need to install the emacs mode for those files.

Developers, of course, can still install it manually from the source repository.

[DanGrayson]

Good point.

[d-torrance]

Personally, I like apt to install everything for me so I can just get to coding without fiddling with installing more things manually. :)

But if Dan uses M2 mode, does anyone use D mode? Perhaps it should just disappear completely? There's a lot of overlap anyway. Maybe add some of the D-only keywords to M2-symbols.el?

[DanGrayson]

It would be nice if D-mode were made to work -- then I would use it again.
