web stuff

[Luka <luka@MIT.EDU>]

mic and i noticed the bmg web pages were broken, so i went
looking.  things to watch out for (fixed by me this time)...

our index.html uses a css file.  i know next to nothing about
css itself, but did find the reference to the css file
mistyped in the index.html, which is what caused the main
page not to display at all.

make sure that you leave appropriate read permission bits set
on files you create/edit.  i think it needs to be either
world-readable, or graphics-group-readable, perhaps requiring
world on index.html, or something... it confused me.  certainly
full-read on everything works so that's how i left it all.

oh yeah, and group write should be on all files too i think,
even tho it can be forcefully bypassed if it's not (unless
it's on a directory!).  i didn't go on to fix things without
g+w, but you should check over your own files for that issue.
