merging PR #152: Voting threshold

#152: Voting threshold

Description:
There should be a voting threshold (it's actually a threshold on the votes _difference_).

Set to 1% of repo followers (currently, that means the difference between 👍 and 👎 should be at least 12).

Prevents things like #138 and #48.

Maybe we can change this later to use a percentage of active contributors instead of (possibly passive) stargazers? Not sure how to calculate that atm though.

:ok_woman: PR passed with a vote of 18 for and 2 against, with a weighted total of 16.0 and a threshold of 1.0.
