Add B1 Riverside into the game as a separate map from B2 riverside

currently, your two choices to play b1 riverside are to play on the riverside b1 exclusive server (which sometime you need some variety in your life so no one is on it) or to have an admin come on to set the map to B1. This makes it

1. more difficult to play b1 riverside

2. more difficult to get better at b1 riverside

which both make b1 riverside less fun. If b1 riverside was added as its own map us new plebians can have the chance to play a bunch of b1 riverside. The distinction might confuse new players at first but it'd be pretty easy to understand once you've played both versions of the map. It'd also be good if B1 riverside was added to the map selection on the official servers.
