[Koha] Koha license upgrade voting method

[Reed Wade]

Feels like we're thinking way too hard about this. It might simplify
things to look directly at our situation instead of getting too
clever.

We're at GPL2. Options are:

  - stay there
  - move to GPL3
  - move to AGPL3
  - some other scenarios that I don't think have been proposed by
anyone other than as a "we could..."

>From what I can tell, moving to GPL3 is not contentious.

>From what I can tell, moving to AGPL3 is mostly not contentious but
has some strong minority opposition.

So, would a meaningful vote be:

  - yes/no I approve of moving to GPL3
  - yes/no I approve of moving to AGPL3

And we could even set the bar pretty high for acceptance (? 80% approval).

This assumes my 'From what I can tells' are correct.

The proportional voting schemes seem to make more sense if we're
looking for more than one outcome--which we aren't. -- unless we want
to have a certain percentage of the code under one license or the
another, that would be kind of cool (no, I'm joking here, don't do
that).
