[Bioperl-l] Small change in UniGene file format

[Andrew Macgregor]

Andrew Walsh pointed out in bug report 1491 that the NCBI *.data files 
now include a version number at the end of the accession number in each 
SEQUENCE line e.g. ACC=BQ190891.1

I have modified the UniGene module to handle this. The resulting Seq 
obj in this case now returns BQ190891 as the accession number and 1 as 
the version. The module can still parse the older format, e.g. 
accession numbers without version info. I hope this conforms to 
conventions regarding accession numbers in bioperl.
