Minor text changes and cleanup

update readme.txt

Clean text going out of bounds in raw restore mode

Fixes: #24

Ready for 1.4d release:

* Fixed bug in card.c that prevented writing to the last block of the memory card, preventing restoring a savegame that would fill the memory card (thanks to undergroundmonorail)
* Fixed bug in card.c that prevented correct block freeing when deleting a file and only was fixed by using the memory card on official software (the wii/gamecube save manager or probably also games)
* Added libogc fix for a bug in card.c (the bug didn't affect GCMM, it was fixed in 1.4b, but I didn't change card.c)
* Changed button presses for single savegame delete to prevent unvoluntary savegame deleting

Disabled __sector_erase() check when raw restoring as some unofficial…

… cards seem to have problems with it.

Corrected typo in buffer checking in raw.c

Note: not updating debug version because the changes don't affect its code
