platform data wiped out

Took me a minute to figure this out, but the browscap module wasn't getting any platform data into the table. The problem is that in the browscap.csv file downloaded, there is no platform data for the top level parent, mostly platform data is just listed for the children. When the browscap module imports, after creating all the entries it then updates all the children with information from the parent entry. Since the platform data is blank for the parents, it gets erased from the child entries. I deleted the parent part from the update database call and the platform data is preserved.
