Update Hash.java

[mpeters-tha]

Changed on equals method to use "instanceof" to check the 2 objects class instead of "obj.getClass()".
This is for when you create a hash using bigInteger contructor which create a Hash object, while if create a hash from an image, the object will be of the hash algorithm type you have chosen, and the equals will return false while the 2 are in fact equals.

Thanks, I'll have a look at it to see if it breaks identity or importing in any other way

Hello,

Do you know if this will be pushed in the master branch ?

I will release a new version this Saturday fixing older issues as well. For a better serialisation it might make sense to also include more class information into the saved state. Next week this issue will be fixed.

Code is ready, but a few tests still need to be written.
