Use lua_pushliteral and lua_pushlstring instead of lua_pushstring, which
avoids Lua having to determine the length of the string.

It wasn't really adding anything since errors raised using luaL_error
are already logged anyway.

In preparation for using an entity/component system for the entities
in the game world, this name will be more recognizable and easier to
talk about.

- Made the current charge being saved.
- Added script binds:
- chr_set_special_recharge_speed
- chr_get_special_recharge_speed
- chr_set_special_mana
- chr_get_special_mana
- get_special_info
- Added special info lua class. Functions:
- name
- needed_mana
- rechargeable
- on_use
- on_recharged
- category
Further the engine no longer sets charge to 0 after using of specials
this allows more flexbilillity (like failing specials).
Changes on the xml database:
- recharge renamed to rechargeable (needed by client and server)
- needed - the needed mana to trigger a special (server only)
- rechargespeed - the defailt recharge speed in mana per tick (server only)
- target - the type of target (either being or point) (server and client)
I also made the lua engine pushing nil instead of a 0 light userdata when
the pointer was 0.
Database update needed.
Change is tested.

Rather than wrapping NPC functions up in coroutines in the Lua side, they
are now managed on the C++ side as "script threads", which are essentially
the same thing.
The main purpose is that the server can now know whether any of these long
running script interactions are still active, which will probably be useful
when adding the ability to reload scripts.

The new function 'checkCurrentMap' will raise an error when no current map has
been set, eliminating the need to do custom error handling all over the place.
This also fixes several functions that would otherwise have simply crashed
when there was no current map.
Also cleaned up some "empty string parameter" checks.

It's a bit embarrassing the way this has gotten out of hand. The error
checking was inconsistent, and in some cases wrong.
A host of new helper functions, starting with 'check' rather than 'get',
perform error handling on function arguments (they will not return when
encountering an error).

Item and monster classes could already be identified by either their id or
their name. Now the explicit values returned by 'get_item_class' and
'get_monster_class' can also be used as parameter.
In addition the above two getters learned to understand all three types of
parameter as well, rather than only supporting a name.

Based on a native Lua table with weak values, so that the user data objects
that are created can be garbage collected when no longer referenced.

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.

inventory.
It permits to open a sell box with every items in the player inventory
as requested by Striker.
Also added different return value support to both the buy selling functions,
and made fixes where relevant.
The test.lua script will be upgraded to show examples in a next commit.
What's left to be done is to fix the inventory handling for both selling
functions. (Sigh...)
