Potential fix for errors related to 'Not enough free blocks' 

changes fs getusage to return 1 additional inode to account for the directory itself
Fixes save creation for at least two games, R8XE52 (Jurassic: The Hunted), STEETR (Tetris Party Deluxe)
doesnt harm save creation in any games that i tested (about 25)

also it is now possible to boot a nand title by selecting the tmd file using File > Open
