Adds support for creating state machines for attributes on any Ruby class

StateMachine::Path#initialize

Creates a new transition path for the given object.  Initially this is an
empty path.  In order to start walking the path, it must be populated with
an initial transition.

Configuration options:
* <tt>:target</tt> - The target state to end the path on
* <tt>:guard</tt> - Whether to guard transitions with the if/unless
  conditionals defined for each one
