Loading order of ansible.cfg

These patches will modify the order in which ansible.cfg is loaded.

Documentation say: ./ansible.cfg > ~/.ansible.cfg > /etc/ansible/ansible.cfg
But it was loaded as: ~/.ansible.cfg > ./ansible.cfg > /etc/ansible/ansible.cfg

It also fixes a type in the changelog where it is referred to as '.ansible.cfg'.
And adds the loading of ./ansible.cfg to the comments in the ansible.cfg file itself, which only stated ~/.ansible.cfg and /etc/ansible/ansible.cfg
