Previously, global function names were defined in the respective XML
definitions of items, monsters and status effects. This was reasonable when
they all had the same state, but now they're sharing the single global
Lua state.
Now the Lua API provides access to the ItemClass, MonsterClass and
StatusEffect instances, on which callbacks for both standard and custom
events can be explicitly set.

This includes the quest reply, post reply, death notification and
remove notification.
Also, Script::Ref was changed from a typedef to a small class,
automating initialization and making the check for validness clearer.

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.

No more Lua state for each status effect, monster, item effect or map. All
scripts are loaded into the same state. This should be more efficient overall
and make it easier to implement dynamic reloading of the scripts in the
future.
Now, this introduces the problem of name collisions between different Lua
scripts. For now this is solved by using more specific function names, like
'tick_plague' and 'tick_jump' rather than just 'tick'. The plan is however
to get rid of these globals, and register these callbacks from the script,
so that they can be local functions without the danger of colliding with
other scripts.

It's easier to just talk about world data and to modify it as a whole.
If there is really a need to separate it, a project can still choose to do
that (and in whatever suitable way). There is no need to enforce this
separation or to do it in our example.

Just defined an inline function to make talking to the player easier.
Would be nice when NPC scripts could look more like this by default.
Also indented with 4 spaces, which we do in C++ so why not Lua files
(the file had mixed 2 and 4 space indentation before).

This can now be done in attributes.xml through the

Based on a templated helper class, MapObject references in Lua scripts are now
full user data objects. Using the '__index' member of their metatable, a
library is associated with it so that member functions can be called directly
on the object.

These scripts could trivially share one script state, since the methods
called on them from the server are not overlapping. This does leave them
open to access each other's global variables, but that's the problem
with global variables.
The one remaining global script file name is now configurable, so that
it may also be set to a script in a different scripting language. The
two related script options are:
script_mainFile (default: scripts/main.lua)
script_defaultEngine (default: lua) - renamed from defaultScriptEngine

At the moment it is the responsibility of the script to make sure any
references to beings passed into script functions are valid.
This means you can't schedule delayed scripts like the one making
maggots say 'Roaaarrrr!!!', since the being might have been removed
before the script gets executed. In the case of this bug the maggots are
removed by some script code testing 'mana.monster_remove'.
We should of course fix the way actor handles are used in Lua so that
scripts can't end up crashing the server.

Made the server handle only one slot type requirement since
it's irrelevant to have more anyway.
Plus, it simplifies the code for both equipping/unequipping.
