fixed: Big::ToDouble(double &) set always +INF (infinity)

when the value was too large (even for negative values)
       (it should set -INF in such a case)
added: some missing methods for converting
       for UInt<>, Int<> and Big<> classes:
       uint ToUInt()
       sint ToInt()
       ToUInt(uint32_t &)
       ToInt(uint32_t &)
       ToInt(int32_t &)
       ToUInt(uint64_t &)
       ToInt(uint64_t &)
       ToInt(int64_t &)
       FromUInt(uint32_t &)
       FromInt(uint32_t &)
       FromInt(int32_t &)
       FromUInt(uint64_t &)
       FromInt(uint64_t &)
       FromInt(int64_t &)
       and appropriate constructors and operators
       *** version for 64 bit platforms are not tested yet ***
added: double Big::ToDouble() /there was only Big::ToDouble(double &) /
       uint Big::ToFloat(float &)
       float Big::ToFloat()
