RE: svn_load_dirs case-insensitive comparisons on Windows

Thanks Ryan for your reply,

Unfortunanlty, there are many different people working on these assets
that are being exported and it might be the fault of the particular user
who is doing the export that they are not using the exact same case when
they modify and re-export the assets (it might even be the case that
they are exporting on different OS's and on Unix breeds perhaps the
exports are always in lowercase?), however it isn't the 3rd party
software that is failing during export so there is no perceivable error
there. In addition, the 3rd party asset creation team is not using SVN
and thus may never realize what is at fault.
The failure occurs when trying to import the content into a vendor
branch using the svn_load_dirs.pl script. Since it is the script that is
failing, it is the script that should be adapted to account for this

I would consider it a user error to be randomly changing the case of
filenames. Users shouldn't do that.

Of course, it may be a 3rd-party tool that's changing the filename
case for the users. In that case, it is a bug in the 3rd-party tool.
