Returns the current fuel level of the turtle, this is the same integer returned by turtle.getFuelLevel(),
that decreases by 1 every time the turtle moves.
Returns the numerical ID of this computer.
This is the same number obtained by calling os.getComputerID() or running the "id" program from lua,
and is guarunteed unique.
Mounts a directory into the computers file system, from a real directory in the Minecraft install folder.
For example: mountFixedDir( "stuff", "mods/mymod/lua/stuff", true ), will mount the "lua/stuff" folder from
your mod's directory into the computers filesystem at the location "stuff", with readonly permission, giving the
computer access to those files.
When a directory is mounted, it will appear in the computers file system, and the user will be
able to use file operation to read from and write to the directory (unless readOnly, then only writes will be allowed).
mountFixedDir can also be used to mount files, for example: mountFixedDir( "rom/apis/myapi", "mods/mymod/lua/myapi.lua", true ) can
be used to have the peripheral install an API onto the computer it attaches to.
Unmounts a directory previously mounted onto the computers file system by mountSaveDir or mountFixedDir.
When a directory is unmounted, it will disappear from the computers file system, and the user will no longer be able to
access it.
