[Control Scheme Option] Prevent rolls while holding modY#1074

Current roll settings:

• default, left stick, right stick, double shield lock

Proposed:

• add modY lock

Why:

• modY has some really cool tech including slow runs, easier turnaround up/down strongs, easier neutral specials while drifting left/right aerial or grounded. This replaced my second shield button.
• right stick roll option (Sol Birdguy’s recommendation) is now less appealing with the addition of grounded item toss.
• Adding modY lock still gives users the flexibility of enabling/disabling rolls on the fly, making grounded glide tosses easier.
• Since you can already prevent rolls with double shield lock setting or with the walkmod button, this won’t give any game-breaking advantages.

Bonus:

• add a setting to prevent platdrop when modY or walkmod are held.
• current behavior while on platforms makes no sense
  • down + modY or walkmod –> stays on platform
  • down + modY or walkmod + SHIELD –> always plat drops (???)
  • would rather they just always prevent plat drops when held

Not sure if it was from a patch or something I missed, but modY works with shield to stop rolls and spot dodges. Great!

Keeping this up for the bonus request to allow for modY or walkmod prevent platfrom drops when shield is held
