findFile should be case insensitive

[FawazTakahji]

If you try to check if a file called "foo" exists but the file name is "Foo" then findFile will return null, but If you try to create/move a file called "foo" then it will be renamed to "foo (1)", so I think it would be better if findFile is case insensitive, or maybe make it optional
