Doc improvements, compilation

["Luís]

In the docs for std.format we have the following example:

     import std.c.stdio;
     import std.format;

     void main()
     {
         auto writer = appender!string();
         formattedWrite(writer, "%s is the ultimate %s.", 42, 
"answer");
         assert(writer.data == "42 is the ultimate answer.");
         // Clear the writer
         writer = appender!string();
         formattedWrite(writer, "Date: %2$s %1$s", "October", 5);
         assert(writer.data == "Date: 5 October");
     }

This does not compile because where it imports std.c.stdio it 
should import instead std.array. Are the docs not being compiled, 
to check for errors? Perhaps that could be improved, by 
automatically compiling all the docs and checking for errors (if 
they all should just compile then it's straightforward, otherwise 
it would be necessary to tag them as 'should compile' where 
appropriate, or by adding the necessary scaffolding to ensure 
compilation).

The js "jump to" headers also seem not to be working well. In 
std.conv I get (in both Chrome and Safari):

     Improve this page _to!TargetType(value) (and not some variant 
of toImpl)." class="button">Page wiki View or edit the 
community-maintained wiki page associated with this page.

In other pages it seems to work, but it is often very slow to 
generate the jump to headers.
