[Mono-list] Determining case sensitive environments

[Charlie Poole]

Hi Chris,

I asked a similar question a while back and it was pointed
out to me that the file system is independent of the platform
and that you can mave more than one file system available
on a machine!

In the end, I made case-sensitivity a parameter to the
methods I was creating, with other overloads that left
off the parameter defaulting to the "standard" file
system for my platform.
