Fix invalid access crash on exit in LimboHSM 
Since #131, `LimboState::_exit()` became a source of potential crashes
if object references are used without a validity check. It's too easy
to miss this, which can lead to game crashing during runtime.

This fix reverts #131 change and proposes alternative approach of
re-activating root HSM upon tree entering if it was previously active.
Note that it's not an ideal solution, as some state will be lost upon
re-parenting: HSM exits and then re-activates and enters its initial state.

Rework HSM transitions bookkeeping 
Fixes a potential rare hash collision situation, and allows additional
attributes to be stored with the transition data in future.

Serhii Snitsaruk 193743e782 Provide the previous state in the state_changed signal 
- Also provide `get_previous_active_state()` method.
- Rename state_changed -> active_state_changed.

Serhii Snitsaruk eaeb57e2d7 Allow `LimboState::dispatch` to be called from inside the hierarchy. 
Improves usability and removes requirement to call this method on the root state (see #49).
