This adds a new graphics type for the Vulkan graphics API. All this does
is to create a vulkan instance and a presentation surface with the help
of SDL.
This is a system for storing arbitrary data in the config file and then
easily retrieving it later on. This has full Lua support for exposing
the available options in a custom UI and changing the values of the
options. This ported some of the existing command line options over to
the new system which is opt-in for the moment by using a mod_table flag.
There were some reports that using a newer launcher together with an
outdated launcher was causing some issues since the new launcher would
write the new config file which would cause FSO to ignore the changes of
the old launcher since the new config file already exists.
This fixes that by adding a check for when the config locations were
last modified. On Linux and Mac it checks when the old config locations
were modified last while on Windows it checks the registry to determine
if there was a change after the new config file was created.
FSO now allows the window title to be specified via game_settings.tbl, some never-used function arguments were pruned at the same time, and fred.rc now receives version information (for the About dialogue and the title bar) from a cmake-generated header, so the version numbers get filled in properly. Speaking of FRED's About dialogue, it now displays the copyright symbol properly.
This makes the debug window resizable and also reduces the default size
to ~80% of the used display. This also makes sure that the main window
has input focus after the debug window was created.
This allows to use a different method of creating and managing the
OpenGL context. This is needed of wxFRED where the OpenGL context is
created by wxWidgets. This will probably also fix#753 since it uses the
old wgl based method of creating an OpenGL context in FRED.
The documentation says that the SDL OpenGL attributes need to be
initialized before a window is created. These changes implement that by
moving the actual SD_Window creation inside the OpenGL setup. FRED only
sets the native window handle to the correct HWND and gropengl uses
that.
SDL2 support multiple windows and differentiates the events for the
individual windows using the windowID field in the events. These changes
check if that window ID belongs to our main window and ignores any
events that don't belong to it. This allows to add another window
without screwing up the rest of FSO with its input.
This will use SDL_GetPrefPath to determine a suitable config directory which will be used for all runtime writing. Additionally all platforms will now use the configuration ini files, the Windows registry will be deprecated. For better compatibility with current installs there is a "legacy mode" which will work like the current install. It will be used as long as the launcher doesn't write the configuration file to the new location. Migrating old installs requires copying the existing pilot files to the new location and copying any existing configuration data.
SDL2 Everywhere, from me and Flaming_Sword. Outstanding issues: FRED integration, project file updates, cleanup.

make sure that we handle background clearing ourselves, fixes several little issues
fix popup warnings to work a bit better and not screw up the game so much or make it difficult to interact with them
