The second pull request for this month is, this time, in the distribution that was assigned to me, Exobrain. In this case, it was a simple PR on dependencies.

First, define the minimum version for Data::Structure::Util, the distribution for which I created my first PR this month, in order to make it pass all the tests in version 5.20 and above. Also, took some time to clean up the C syntax.

Then, remove some dependencies that seems no longer needed from dist.ini (were hard coded) and also define a minimum version for a required module directly in the use statement.

So, a simple PR, but one needed (there were some comments requesting this change, as well). You can see it in all its glory (cough!) here: https://github.com/pjf/exobrain/pull/62

Asked NeilB to mark this month assignment as complete but, if time permits, I will prepare a more interesting PR.
