Revert "LuaTable: remove unused GetMap() function"

This reverts commit 15bf44506a7c6ea515595566c4f994fd32549b4e.

Conflicts:
	src/LuaTable.h
Fix debug.deprecated when there isn't enough data.

Shiptype: store the slot informations in an map<string, int>

This allows the system to decouple ship definition from the rest of the
Lua, thus returning to the previous state and easing any future
migration of the ship definition file format.

Conflicts:
	src/LuaModelViewer.cpp
	src/Pi.cpp
	src/Ship.cpp
	src/ShipType.cpp
	src/ShipType.h

Add a new lua library EquipSet.lua to handle equipment changes.

This new Lua class will leave alongside the old C++ infrastructure for a
little while.

Conflicts:

to lookup its slots, and fixes up a few modules to work with the new
system.
