Release D 2.104.0

[Iain Buclaw]

Glad to announce D 2.104.0, ♥ to the 38 contributors.

This release comes with 11 major changes, including:

- In the compiler, User Defined Attributes now parse template 
arguments.
- In the standard library, `std.typecons.Rebindable` now supports 
all types
- In dub, new properties `cSourcePaths` and `cImportPaths` have 
been added to pass C sources and add additional search paths for 
C headers to the compiler.

As always, you can find the release binaries and full changelog 
on the dlang.org site.
