[boost] Patch for signals/trackable.hpp

[Markus Schöpflin]

Attached is a small patch for signals/trackable.hpp. According to 7.1.1(8), the mutable keyword cannot be applied on reference members and Visual Age flags this as an error. I just removed the mutable keyword an it compiles fine afterwards.
