DMD Beta 2.105.0

[Iain Buclaw]

Glad to announce the first beta for the 2.105.0 release, ♥ to the 
34 contributors.

This release comes with 10 major changes, including:

- In the compiler, assignment-style syntax is now allowed for 
`alias this`.
- In the library, integration with the Valgrind memcheck tool has 
been added to the garbage collector.
- In dub, there's a new `--d-versions` CLI flag.

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