Replace 'brogrammer' reference

https://github.com/computeranonymous/computer/pull/39 for Reasons

Currently this doesn't replace it with anything; I suspect a replacement clause is needed, but don't know what.

As for Reasons:

From @russss https://github.com/computeranonymous/computer/pull/39#issuecomment-25318944:

> It's clear from this thread that we're not particularly sure how to define "brogramming". I'm increasingly unsure that the people who we want to exclude would identify as "brogrammers" anyway.
>
> I think the main thing we want to avoid from "brogrammers" is casual sexism. These rules already cover that.

> I'm /mostly/ happy with this commit. I understand why we don't want to use brogrammer/dudebro, but i think we're missing out in that "Boys will be boys" is not welcome, people are expected to be adults and treat each other with respect*
