Fixed bug 2072 - Make OS X's filesystem calls use -[NSString fileSystemRepresentation]

C.W. Betts

The recommended way of getting a file name that POSIX file APIs can open in OS X when using an NSString is -[NSString fileSystemRepresentation]. However, the current filesystem API in hg uses -[NSString UTF8String].
