Version 0.9.1 Update

With beta testing underway, starting from this update, info will be about the main game. All changes also apply to the demo, unless specifically stated.
Version 0.9.1 Update Notes:
- Added an option for auto bomb in Arcade Mode; auto bombing activates only when down to the last armor point and disqualifies the score from the online leaderboard upon its first use.
- Added a quick mission restart in the pause menu for early mistakes in a run; this option only appears during mission 1 in Trial and Arcade Modes but is selectable for all missions in Training Mode.
- Reduced the player helicopter hitbox slightly; the actual area is now smaller than the cockpit frame but still too large to dodge through very tight patterns.
- Increased the hitbox of small tanks slightly.
- Auto fire will resume firing if still held down when the focus shot is being used but the focus counter drops to zero.
- An active game will pause when any controller is disconnected.
