[boost] [random] Update for better TR1 compliance

I've checked in changes to the Boost.Random library that add
constructors and seeding for both

   template<class Generator>  and  unsigned long

arguments, thereby moving Boost.Random one step further towards TR1
compliance.

The random_test.cpp program now has basic tests for this feature.

In order to guide overload resolution, I've used boost::enable_if<>
and type traits to make sure that integral arguments don't
try to call the "template<class Generator>" overloads.  This could
mean decreased compiler support, sorry.

It works for me with gcc 3.4.3.
