Fixed Binary[16] Index

[Stefan Von Torklus]

Thanks for the answer. I already noticed, that it works, if you have no index.
It's right, that it is really uncommon to use a ByteArray for searching.
But if you need an identifier, which is globally unique, it would be hard to do this 
with a long or longlong.

I'll give it a try to split this value into 2 ULLong Fields. If the speed doesn't fit the need of the application,
I would add a feature request or need to work with another solution. 
(unfortunately... 'cause I used valentina within my last 3 projects and it always works fine!)

Greetz,
Stefan
