Revamp of CandyDOC

[Eldar Insafutdinov]

CandyDOC has not been updated for about 6 years, and despite its 
usefulness its current state was rather sad. Overall look was 
awful; colours, font sizes, everything just was not right. D 
allows some very beautiful code, but the look and feel of 
documentation is not on par. Anyway, I gave it a bit of a refresh 
(which was in fact a major refactoring) and here is an example 
http://eldar.me/candydoc/algorithm.html . Among new features is 
also instant filtering. You can grab the sources at 
https://github.com/eldar/candydoc . There is still a scope for 
improvements: adding links to the subsections and ideally 
producing links to the source code. For that ddoc needs to output 
line numbers of declarations which I am not sure it does, but 
that can be added.

Cheers
