Partitions and cursor restore

This release cleans up the code a bit and makes debugging easier using nxlink.
The following new features were added:
Support was added for the user and system partitions on the nand. Be careful when doing things here as you could brick your system or corrupt save data.
The cursor will now remember it's position when going up a directory (pressing b).
If you create a new folder but the name already exists it will append a number to the folder name (this works the same as creating new folder in Microsoft Windows).
