[Hotstorage-chairs] Hotstorage latex style file

[Julia Lawall]

Hello,

Your required hotstorage style file is quite out of date.  The ACM style
no longer makes the fully capitalized section names.  It's probably too
late to do anything for this year, since people are close to submitting
their papers, but it would be good to do something such that the problem
doesn't get propagated from one year to the next.

thanks,
julia
