Merge pull request #1 from tonsV2/master

Allow zero-priced cart
Allow zero weight shipping. Thus only Handling Fee is added to the final price.

Replace short php tags with their full equivalents to make code more portable
Fixed: first time saving settings with fresh install does not save anything while reporting successful saving.
