Redesign currently implemented qualified constructor concept.

http://wiki.dlang.org/DIP49
Improved points from version 1:
- Swap meanings of 'this(this) inout' and 'this(this) const'
- Inout postblit now covers all cheap (== not rebind indirections) copies between same qualifiers

This is awesome, maybe I'll be able to use immutable in my code, thanks to this and your bugfixes (opAssign)!

One suggestion though - maybe @unique would be better than const for unique postblit/constructor, I think static confusion is an important lesson from the past.

I agree, `@unique` attribute looks more clear.
BTW, we can use `unique` keyword for unique postblit/constructor. Also, we can use this keyword for unique storage class of variables and related issues.
