Subject: Add support for negative votes for categories
X-Git-Url: https://git.cworth.org/git?p=empires-server;a=commitdiff_plain;h=678fbabe0f69470625606f59b84e87ae1d60c110;hp=23ab0d1f2fe34ae413a3a37dc6c01855148f16b9

Add support for negative votes for categories

Just like the positive votes, the endpoint allows toggling and the
storage maintains that each player can only vote for (or against)
once.
