[Mono-list] File IO error

[Mike Gray]

I believe the reason these tests are still not working is that they are 
trying to access/create/delete/etc. files in "filetest" directory.  Since 
this doesn't exist, well, they are failing as expected. :)

Here is a patch to FileTest.cs that uses the "resources" directory you 
created instead of "filetest".  With this patch, all of the tests written 
(which is not many at this point, but I will work on that over time) do run 
and work.

Let me know if this is what you had in mind for the resources directory or 
if you had something else going forward...
