Sorry, that patch was bzip2-compressed -- forgot to change the filename.

>I really, really wish I had thought of this _before_ the big merge, but

>(privately, of course) and I'll fix them up and mail them back ASAP.

>This changeset updates the single-Lua-state script interface to allow
>scripts to be written in a manner compatible with the original Aquaria
>engine.  In particular:
>
>- The "v = getVars()" boilerplate line at the top of each script has
>  been changed to read "if not v then v = {} end".
>
>- The getVars() script function, added as part of the single Lua state
>  implementation, has been removed as it no longer serves any purpose.
>
>- Scripts which previously included the "entityinclude.lua" file (which
>  was removed as part of the change to a single Lua state) have been
>  modified to once more include that file, but only when running under
>  an earlier version of the Aquaria engine.  The entityinclude.lua file
>  itself has also been restored from the _unused subdirectory for use
>  by earlier versions of Aquaria.
>
>All scripts have been updated accordingly; as of this changeset, the
>scripts should work with a vanilla (pre-open-source) Aquaria build.
