Turns out I mistook @celticminstrel's opinion that we should use include guards over pragma (737916e).
Since all major compilers support `#pragma once`, there's no reason not to use it.
For future mergability reasons, this excludes src/spirit_po and src/xBRZ. It also excludes src/boost-patched.
* Moves load_game_exception to savegame.hpp and cleans some #includes
* Removes the load_game_exception statis members and replaces them with
a non-static load_game_metadata member.
* Adds loadgame::DIALOG_TYPE to remove the gui1 dependency.
* Fixes loading of replay saves.
* Adds soem mising override specifers in savegame.hpp
In initial commit of the new lua kernels, I introduced a problem
by trying to use luaW_pcall and lua_pcall interchangeably via
polymorphism. This doesn't work because their return types don't
match, and it's alot of work to change luaW_pcall syntax. Besides
this there's no reason we can't use the custom error handler
everywhere.
This commits adds protected_call and load_string functions to lua
kernel base. These are an intended replacement for luaW_pcall,
and replace the "run" function. They do better error reporting
and allow to specify an error handler.
The error reporting is very flexible -- by default we select a
an error reporting function associated polymorphically to the lua
kernel, so the in-game lua kernel can send chat messages, and
others can do something else. However an arbitrary handler may
be specified, and exceptions instead of logging may also be
requested.
Implemented sticky exceptions that can be rethrown at will.
Used them to ensure that quitting the game, loading a new game, and
leaving to title screen, work correctly when WML is being executed.
