D 2.062 release

[Kapps]

Personally, I just wish there was a quick blurb at the top of the 
changelog indicating the highlights of this release. For example, 
with 2.058, the very first two lines of the changelog were:
"Add new => lambda syntax."
"Allow 1.userproperty syntax. NOTE: 1.f is no longer a float 
literal, add a 0."

You can look at that and decide "Awesome, new lambda syntax and 
UFCS!". You get a quick 10-20 lines indicating what you need to 
know about that release, what's interesting about it, and what 
the new features or most important bug fixes were. For the people 
who care, you can then see bug fixes / larger list of changes at 
the bottom (I personally don't have a preference as to whether 
they'd be on the same page or just a bugzilla link). However the 
really important thing is the quick blurb at the top.

For example, with this release, something about how 'in ref' is 
now supported, how you can document unittests and have them 
appear with the documentation of the above symbol, improved JSON 
output, and unittests being allowed in interfaces. This is just a 
quick 10 line overview of some of the highlights of this release. 
Not necessarily just new features either. For example, if example 
bug#314 was fixed, there is absolutely no way I would know about 
it given that it's buried in the list of bug fixes, even though 
it has affected almost every single D user at one point and would 
definitely be considered a highlight.
