Update Shine event system to simplify shine event handling

[degremont]

The current event handling system manages event as a simple name, like ev_starttarget_done, ... Due to this, each Shine EventHandler must declare a lot of different callback method even if in most cases the process is the same for each.

This ticket groups all effort to rewrite this part of code to simplify this to a unique or very few callbacks.
