Drop D1 support now?

[David Nadlinger]

Hi all,

my original plans back in December were to make the next 
(upcoming) release the last one to support D1, so that there is a 
LDC 1 version available that is based on the last official 
frontend release.

However, the new D1 frontend still has not been merged, while at 
the same time we should really push for a quick 2.062 merge and 
subsequent release. As it looks like the general interest in D1 
has pretty much faded by now - there has not been a single 
D1-related question or issue report since the last release -, 
what do you think about dropping D1 support from Git master very 
soon?

The last version to still have a dmd/ in working order would get 
branched off, so that anybody could continue to work on it if D1 
is still of interest to them.

David
