Ddox: Show exact source code links for multiple declarations

[wilzbach]

If there are multiple declarations, the source code link should go to the first declaration - not to the header of the file.

Example e.g.: http://dlang.org/library/std/algorithm/comparison/among.html

[wilzbach]

In case someone was wondering what this does:

Before

http://dlang.org/library/std/algorithm/comparison/among.html
Source code link points to: https://github.com/dlang/phobos/blob/master/std/algorithm/comparison.d

After

http://dtest.thecybershadow.net/artifact/website-99c70ce923b2fb7f7dfc8aec6a9d04c3a5f1406f-b7c033f85ecbb7d3947e28b0db7d1c5e/web/library-prerelease/std/algorithm/comparison/among.html
Source code link points to: https://github.com/dlang/phobos/blob/master/std/algorithm/comparison.d#L85

I think this is a really trivial change (one char!) that sits here for more than a month. @CyberShadow could you please help and have a look?

[CyberShadow]

Sure why not. Not familiar with the code but the diff looks fine to me.

[wilzbach]

Hmm this had the disadvantage that it creates a huge diff for even small changes as all line numbers are shifted. Should we for Digger builds turn this off?

[CyberShadow]

Link to example diff?

Digger builds the live website which would mean they would almost never be visible there. I guess you meant DAutoTest. We already do this for NODATETIME.
