[R] Shapefiles package upload

[Benjamin.STABLER@odot.state.or.us]

I uploaded version 0.3 of the shapefiles package to CRAN earlier today.
Version 0.2 had a bug that omitted the decimal precision in numeric fields
so some programs (such as ArcGIS) would not parse the fields correctly.  I
also added an argument to write.dbf to swap "." with "_" since ArcGIS does
not permit underscores in field names.  Let me know if you run into any
other problems.  Thanks.
