[fprint] pam_fprint 0.2: some improvements

[Diego Zuccato]

Hello all.

I just started working with libfprint.

The first thing I wanted to do was giving better security w/ my reader 
(uru4000b), since it keeps the image of the last acquired finger on its 
window (someone could easily "steal" it).
The trivial workaround is require more than one finger to login. And 
since I was there, I added some options for pam_fprint:
- finger=[-1-9] : force the module to ask for the given finger (-1=auto)
- nfingers=[1-10] : require the use of N different fingers
- randomize=[1|0|true|false...]: randomize the required finger

nfingers implies randomize=true and finger=-1; randomize=true implies 
finger=-1;

If no parameter is specified, the usual behaviour is used.

Hope it's interesting for someone else, too.

All comments welcome! :-)

BYtE,
  Diego.
