Use callbacks for handling character death and respawn

Rather than relying on the availability of global functions with certain
predefined names, the Lua script now calls API functions to set which
function should be called on these global events.

This mechanism should make it easier to avoid name collisions in the global
namespace, which is important now that there is only a single script state.
For these global events this was not likely to become a problem, but this
solution can also be used for callbacks on specific item or monster types,
or even allow setting callbacks on certain instances.
