ZF2-164: Incorrect territory data for Vietnam

Description

File Zend/Locale.php, line 174, I think the correct territory data for Vietnam should be 'VN' => 'vi_VN' instead of 'VI' => 'en_VI'

Comments

VI are Virgin Islands not Vietnam (VN)

Thank for your response, so is it fine to add 'VN' => 'vi_VN' ?

'VN' => 'vi_VN' already exists in master branch.

Thanks, I was not aware of zf2 in github.
