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

A client can craft something using the @craft command.
The command needs a list of item names and amounts. The gameserver checks
if the character has these items in the inventory and then passes the list
together with the character handle to the lua script function on_craft in
the script file scripts/crafting.lua.
This function can then be used to evaluate if the list is a valid crafting
combination and when this is the case take or give items.
Implemented two example crafting scripts there, one which enforces exact
item order and amount and one which doesn't. Both are disabled per default
and one needs to be enabled by uncommenting a line.
Also gave the player group permission to use the @craft command in
permissions.xml and added two new items (wood and iron) required for the
example crafting combination.
Resolves: #333

* Rely on the fact that a std::string is empty by default
* Use std::string::empty() rather than comparing to ""
* Construct with std::string() rather than from ""

Also added an header to the autoattack.{h,cpp} files.
Big but trivial fix.

Now the Lua file name shows up in the error message and stack traceback,
or the map file and object name in case of a script embedded in a map
file.

The backtrace is printed by using debug.traceback as error handler when
calling Lua functions. At the moment it still looks pretty ugly since
Lua is not aware of the file names of the scripts (to be fixed).

Added script call for getting the cost of a special (recharge only for now)
Deleting specials works server-sided but the client isn't informed about it properly. Specials without recharge cost don't appear for the player. Both of these features require an additional netcode message.

Also updated the headers to refer to the GPL by URL instead of
suggesting to contact the FSF by snail mail, as per the latest
GPL usage instructions.

Same as for the client.
