Python 2.6 support

[adrienverge]

Hi,

Since today, pathspec is used by yamllint, which is used by Ansible, OpenStack and others.

The problem is: all these software must support Python 2.6, but pathspec currently doesn't. This leads to issues like adrienverge/yamllint#55 and ansible/ansible#26186.

In your opinion, what's the amount of work needed to support Python 2.6?

@adrienverge As much as I think everyone should be migrating to Python 3, supporting Python 2.6 would be trivial. It looks like there's that dict-comprehension and a utility method that needs a slight tweak. So very little work is needed.

@adrienverge Python 2.6 support has been added. I tested it through tox and everything seems to be in order.

@cpburnz thanks a lot!
