[UU] Option to Vote in more Vanilla Bots, or ramp up difficulty

[MEESTER SoupCan]

The new addition of bots to Uber Upgrades was a nice addition to help keep the servers somewhat active when player counts are low, but the 2 - 3 bots per team can make it quite slow after a bit of time. It would be nice to have the option to vote for more or less bots to keep things moving, and not having to wait for the next bot to come out after 5 - 10 seconds, which can add up. An ability to vote for more or less difficult bots would be convenient as well, in case we get too overpowered to where bots are too easy to kill, and don't offer a great enough reward to keep up with the upgrade prices.
