wrong mimetime for gzip files

[liedekef]

In the file wp-includes/functions.php, function wp_get_mime_types(), the mimetype for gz|gzip is indicated as "application/x-gzip", while fileinfo (and /etc/mimetypes) return "application/gzip".

Also, it seems this line is missing tgz, so I would suggest changing this from:

'gz|gzip'                      => 'application/x-gzip',

to:

'gz|gzip|tgz'                      => 'application/gzip',
