patch 0-2-2b: Skirmish and Big Base

This patch includes 2 new game modes, and a bunch of bug fixes.

There's a new practice mode

Big Base, and Skirmish mode.

Added some info about our upcoming DLC

Super Ace!

New Features:

-- Big Base: new practice mode where you and your opponent start with a large base and a bank of resources, but there's nothing to mine off of the map. Practice building and controlling a large army.

-- Skirmish mode makes it easy to play standard matches against the AI.

Bug Fixes:

-- Rust Outlaw: Turbo was setup wrong and was uncastable.

-- Rust Champion: Treads were animating backwards.

-- Some projectiles were not spawning visual effects if they impacted the edge of the map.

-- Sandbox mode would occasionally not stop matches properly.

-- Sandbox mode would incorrectly list an opponent when there was none.

-- Some options weren't taking effect until after the option panel was opened.

Other Changes:

-- Keyboard hotkey presses now make UI sounds and are visible on the command card.

-- Improved materials on some city-buildings (visible via arena-cam).

-- Handful of small changes to the new menus.

-- Some changes to opponent AI, they're better at base layouts, they scout more often, and they are more efficient with their inputs.

-- Leaderboards: now properly show the last-seen value.
