[Ipopt] Ipopt + MA27 compiled for Visual Studio 2008

[scanpat at free.fr]

I want to use MA27 because it seems to be *threadsafe* :
http://list.coin-or.org/pipermail/ipopt/2013-May/003370.html

"- localized global variables in TaggedObject and RegisteredOption,
   so that Ipopt should now be threadsafe as long as Ipopt objects
   (esp. SmartPtr's) are not shared between threads and a threadsafe
   linear solver is used (e.g., MA27) [#167]"

Hi Tony,

I think I've got a working setup for putting the precompiled libhsl.dll 
on the site, I've just not had time to do so.

I'll see if I can make time this afternoon.
