[Developers] /wikipedia/en_id not giving results for redirected ids

[Shug Boabby]

But this advice contradicts what Freebase have previously advised...
to use the WPID instead of the Wikipedia Name. Now you're saying that
for future proofing, only the Name can be used? I'd strongly suggest
that Freebase store the redirected WPIDs as well as the names.

Also... what is the formula to change between the Wikipedia Names in
the WEX files and the names in the Freebase API? Is it simply a case
of changing spaces to underscores, or is there other magic? I'd also
strongly suggest that this be made consistent in future dumps.
