`Frontend Label` fixed for indexed array

I made integration c# code with magento [SOAP](http://www.magentocommerce.com/api/soap/catalog/catalogProductAttribute/product_attribute.create.html) . I tried to insert new product attribute but the error "Frontend label is not defined" popped up.

The problem was SAOP array started with `0` index and `catalogProductAttributeFrontendLabelEntity[]` in .NET Entity array started with `1` index. So I added this code for fixing index. This code makes reindexing the frontendLabel array.
