PR for #52

[Decipher]

Given the non-templatiness of this template, could this become a generic extension template with two vars?

{{ extension }} & {{ extension_extras }}

[thom8]

Another option would be to use -- http://docs.ansible.com/ansible/blockinfile_module.html

I think we should try to make this a role so it can potentially be reused by other projects.

/ansible/roles/beetbox-php-uploadprogress

Once stable, we could eventually push these back to galaxy so other Ansible projects can also reuse.
