[fprint] validity news

[Daniel Drake]

I heard from some people at Validity, the manufacturer of the VFS101 and 
other sensors that have started to become popular.

They apparently have a library for linux now, which they wanted to 
integrate with fprint, but we came to the conclusion that this is not 
possible because their library is closed source and they are not willing 
to share.

But for those who really want to use their hardware, there may be some 
proprietary code appearing soon, or maybe you can ask them for it by email.
