Bump stable DMD and DUB version

[wilzbach]

With DUB 1.6.0 (part of the DMD 2.077.0 release), DUB will retry
downloads from the DUB registry and alternatively use fallback mirrors.

core.exception.RangeError@/home/dtest/DAutoTest/work/home/.dub/packages/ddox-0.15.18/ddox/source/ddox/parsers/jsonparser.d(469): Range violation
----------------
??:? _d_arrayboundsp [0x9de042]

so that error comes from the outdated ddox version which we use. Upgrading ddox to 0.16 solves this, but sadly we are blocked on this #1891 :/

Why are we not using the DMD we just built to build the docs from the master branches of other components?

Because I think Martin wanted to lock the DMD version (?)
I'm more than happy to drop the download of DMD_STABLE if we can do so, but for now we can finally do this simple bump. With this bump we will upgrade DUB to 1.6.0 which contains a mirror of code.dlang.org. Thus this will hopefully result in less random failures on DAutoTest...

So yeah, we should really use master/stable (aka latest release) in the future

For the most part, the improvements are across the board, though there were some regressions, e.g.:

For some unknown reason to me, the nothrow attribute vanished.
