Double-check for spaces

When populating the products-default template, double-check for spaces at the beginning and end of Product names (ie "name" column), Set names (ie “set1/2/3” columns) and Series names (ie "series/subseries" columns). If the terms don't match exactly, you risk encountering the following issues if not others:

• Titles won't be assigned to Set

• A new Series will be created that looks very similar to an old Series
