ansible: Update upstream URL
ansible: Add ansible-git to conflicts
ansible: backup /etc/ansible/ansible.cfg if it exists
ansible: Secure some variables

Make sure we're properly quoting shell variables, and using {} when
mixing variables with other text.
ansible: Include example ansible.cfg in package
ansible: Optmize package according to Arch's Python Package Guidelines

We use -O1 in addition to --optimize=1, which is redundant.  Arch's
Python Package Guidelines use --optimize=1, so let's do that.

See: https://wiki.archlinux.org/index.php/Python_Package_Guidelines
ansible: Minor updates for 1.2 upstream changes

Copy library/* and examples to package.
ansible: Copy all man1 and man3 manuals to package

I hadn't noticed that by statically naming the man1 files we were
missing man pages for ansible-doc, ansible-pull, etc. Also, we were
completely missing the man3 pages for ansibles modules, like yum,
apt, ec2, etc.
ansible: Install readme and license from distribution
ansible: Update package to 1.2-1
