* Include directory nodes in FSList sent to detectGames
- This is required for correct detection of toon.
* Don't add / at the end of directories found in getChildren
- It looks like that behaviour was removed from posix-fs a long
time ago, and now there's apparently code depending on directories
_not_ having a / at the end of their name...
* Treat games detected in subdirs as duplicates
- This is a workaround for a detection bug in toon; it will incorrectly
detect the game in the MISC subdirectory as well.
* Don't avoid directories called "install" in the game selector
- I don't know if the original reason for ignoring "install" is still
valid, but the code for doing do so was broken anyway.
short-circuit any call to openForWriting(). Also, directories and
non-existing files can't be opened for reading either, so just
return 0 for those.
