My fault for skimming over that information in the datasheet. The 
28F004S5 has a command sequence to unlock blocks; which this patch 
creates unlock_28f004s5. Unlock_28f004s5 checks if the master lock isn't 
set, and then initiates the Clear Block Lock-bits. This might (should ?) 
be split into a printlock and unlock_28f004s5 which should only contain 
Clear Block Lock-bits.
