[Bioperl-l] Rounding off to 100% in Tools::Blast::Sbjct::frac_identical()

I guess I left it at two digits of precision because I always try to 
preserve backwards-compatibility.  Maybe someone relies on the fact that 
there are only two digits (i.e. they print out the string directly).  But I 
think it would be nice to have three digits, so I'll go ahead and change it.

But I'm still going to round .9996 to .999 rather than "1.000".
