Title: Simple write support and array like accessors.

I've added simple write support for all tag types. All values are converted to strings without type check.
Iptc, Xmp and Exif Data classes have array like accessors to get single values.

Tests are included and passing with Ruby 1.8.7, 1.9.3 and REE 1.8.7 on Linux.
