changeset 30:91901960eac4

Adding the rest of the matrix scanning modes - Not tested yet - Added bug fixes for the scanCol and scanRow methods - Merged in the powered versions of scanCol and scanRow - Added the scanDual, but still needs heavy testing - The scanDual uses twice the memory per key, so it can only scan half as much compared to the other scan modes
