net-mgmt/seafile: 5.1.4 -> 6.0.0

This is an update for seafile to the latest version, 6.0.0. This
major version update has only minor fixes.

Recently they're was a debate regarding Seafile Ltd. being forked
by GmbH. After reading several articles and exchanging emails, I
have determined that the best path for FreeBSD to take would be
that of Ltd. I'm sorry if this upsets anyone.

• Updated to 6.0.0 o add replace parameter to move_file api o [setup-script] check user host when check user exist for mysql o add progress for download dir/multi o add remove_group_repos api
