* Ely: added physics Ghost component. Yo be completed.
* Ely: Ghost component: started implementation.
* Ely: tinyxml2: update.
* Ely: added "Common" family and "Default" component.
* Ely:TODO: refactoring sending events by some components.
* Ely: corrected bugs about actual event sending behavior by CrowdAgent,
SteerVehicle, CharacterController, Vehicle components. TODO:
implementation of discrete sending mode besides the actual continuous
one.
* Ely: tinyxml2: update.
* Ely: event sending behavior changed (actually for CrowdAgent,
SteerVehicle, CharacterController, Vehicle components): instead of delta
frame, now the frequency of event sending can be specified.
* Ely: setting frequency on event throwing works. TODO: let the first
event to be triggered even in low freq conditions.
* Ely: components event throwing: now the first event is thrown as soon
as the component enter in the specific state, while following ones are
thrown at the given frequency.
* Ely: tinyxml2 update.
* Ely: some corrections.
* Ely: tinyxml2 update.
* Ely: continuing to implement Ghost component.
* Ely: Ghost component implementation completed. TODO: testing.
* Ely: started Ghost component TEST
* Ely: started Ghost component TESTing: doesn't work!
* Ely: Ghost Physics component: tests completed successfully!
