Change all includes to start at the base instead of assuming the directory where included from.
This makes it more apparent exactly which header has been included, since many have the same name.
This also allows moving all header files out of the src directory.
Do not change the released Lua source code. Lua is written as standard C, but we compile it as C++ so we can use exceptions. Change the call sites to avoid the warnings about using a C cast instead of static_cast<int>().
NB: The changes to Wesnoth C++ code will be required to upgrade to Lua 5.3, anyway.

Fix compiler warnings.
Lua deprecated luaL_typerror. Wesnoth needs it. Traditionally this was handled as a by-hand edit to the Lua source kit. Refactored into Wesnoth as luaW_type_error.
Some explanations:
- savepng uses setjmp, so I changed it to C; this guarantees that someone does not accidentally introduce a C++ object in it (unlikely though that is)
- The loop in multiplayer.cpp seemed intended to allow the command-line to request repeated plays, so the break was removed rather than refactoring it to an if statement
- Some uninitialized structs were changed to be zero-initialized
- Use luaW_toboolean instead of lua_toboolean
- Needed explicit constructor for vconfig iterators, since their only member is const
