* Bugs and Issues to Address
* --------------------------
* - -gfx-state crashes when ENABLE_DEBUGGER is also enabled:

* - Need to address all the stale TO-DOs below and clear them out :)
*
* To Do Before Next Release
* -------------------------
* - Thoroughly test config system (do overrides work as expected? XInput
* force settings?)
* - Remove all occurrences of "using namespace std" from Nik's code.
* - Standardize variable naming (recently introduced vars_like_this should be
* converted back to varsLikeThis).
* - Update save state file revision (strings > 1024 chars are now supported).
* - Fix BlockFile.cpp to use fstream!
* - Check to make sure save states use explicitly-sized types for 32/64-bit
* compatibility (i.e., size_t, int, etc. not allowed).
* - Make sure quitting while paused works.
* - Add UI keys for balance setting?
* - 5.1 audio support?
*
* Compile-Time Options
* --------------------
* - SUPERMODEL_WIN32: Define this if compiling on Windows.
* - SUPERMODEL_OSX: Define this if compiling on Mac OS X.
* - SUPERMODEL_DEBUGGER: Enable the debugger.
* - DEBUG: Debug mode (use with caution, produces large logs of game behavior)
