[Bioperl-l] SeqStats.pm - correction to Mwt calculation

The protein molecular weights calculated by SeqStats were wrong as the
calculation ignored the water eliminated during peptide bond
formation.

I've fixed this and changed the aa Mwt table to 2 dp and taken water
as being 18.015. The final weight is rounded to the nearest whole
number. The results now agree with EMBOSS pepstats, Artemis and my
Perl libs.

I haven't checked through the nucleic acid Mwt code yet, so this
change is just on the development branch in case I've broken
something.
