DOOM FILESYSTEM

All of Doom's data access is through a hierarchical file system, but the contents of 
the file system can be transparently merged from several sources.

A "relativePath" is a reference to game file data, which must include a terminating zero.
"..", "\\", and ":" are explicitly illegal in qpaths to prevent any references
outside the Doom directory system.

The "base path" is the path to the directory holding all the game directories and
usually the executable. It defaults to the current directory, but can be overridden
with "+set fs_basepath c:\doom" on the command line. The base path cannot be modified
at all after startup.

The "save path" is the path to the directory where game files will be saved. It defaults
to the base path, but can be overridden with a "+set fs_savepath c:\doom" on the
command line. Any files that are created during the game (demos, screenshots, etc.) will
be created reletive to the save path.

If a user runs the game directly from a CD, the base path would be on the CD. This
should still function correctly, but all file writes will fail (harmlessly).

The "base game" is the directory under the paths where data comes from by default, and
can be either "base" or "demo".

The "current game" may be the same as the base game, or it may be the name of another
directory under the paths that should be searched for files before looking in the base
game. The game directory is set with "+set fs_game myaddon" on the command line. This is
the basis for addons.

No other directories outside of the base game and current game will ever be referenced by
filesystem functions.

Because we will have updated executables freely available online, there is no point to
trying to restrict demo / oem versions of the game with code changes. Demo / oem versions
should be exactly the same executables as release versions, but with different data that
automatically restricts where game media can come from to prevent add-ons from working.

If the "fs_copyfiles" cvar is set to 1, then every time a file is sourced from the base
path, it will be copied over to the save path. This is a development aid to help build
test releases and to copy working sets of files.

The relative path "sound/newstuff/test.wav" would be searched for in the following places:

for save path, base path:
	for current game, base game:
		search directory
		search zip files

downloaded files, to be written to save path + current game's directory

The filesystem can be safely shutdown and reinitialized with different
basedir / cddir / game combinations, but all other subsystems that rely on it
(sound, video) must also be forced to restart.

"additional mod path search":
fs_game_base can be used to set an additional search path
in search order, fs_game, fs_game_base, BASEGAME
for instance to base a mod of D3 + D3XP assets, fs_game mymod, fs_game_base d3xp
