Support dub's new dub.sdl project format

[PetarKirov]

Now .sdl is the default format for new projects generated by dub init.

• SDL (Simple Declarative Language) reference
• dub.sdl package format

Is there any rational decision behind enabling sdl? They might have discussed this on the forums or in irc, but I haven't read any of it

It was mostly about having comment support without using a json subset

[aBothe]

& a less strict language syntax. Okay, makes sense.

[PetarKirov]

@aBothe Here and especially here you can read more about the decision to go with SDL.

[extrawurst]

any ETA on this ?

[aBothe]

Okay, so I put a hand on this.. I think today + some hotfixes tomorrow.

[aBothe]

Finished a first approach for the sdl parser. Let's see :)

[extrawurst]

Is this in a mono-d release already ?

[aBothe]

Not yet..I'm just too lazy and underpriorizing mono-d development currently :/

[aBothe]

Now it's been established. Huge sorry for all the time I didn't do anything.
