[Open Assets] Momentum+ Mighty/Trip Bounce Fix

• All aerial states (Jumping, Flying, Gliding, Bouncing, etc.) now share a thrust factor that is as close as possible to half their grounded thrust factor in response to a reviewer.
• Spin steering on the ground has been slightly nerfed to match being in the air. This also fixes Vector's drawangle during Rev Roll.
• You can now Spin Dash while Skidding.
• Momentum now applies properly when underwater.
• Ability Refresh now applies to Spinning in the air, allowing you to act out of the move by landing on an enemy.
• Max Dash Speeds (For Spin Dash characters and Amy) are now properly reduced to 36*FRACUNIT underwater to match the Thok and prevent cheesing.
• Max Flight Time has been increased from 2 seconds to 3 seconds.
• Knuckles' Glide Landing no longer slows him down if he's moving slower than his normal speed.
• Landing during Amy's Hammer no longer cuts speed (I don't even know how that happened).
• Amy's Hammer Jump now puts her in the Spin Jump state.
• Jumping while Spinning when using Amy or Fang now puts the player in the Spin Jump state.
• Cancelling Vector's Beat Bash by failing to time a wall hit twice or by pressing Spin now puts you in the Spinning state.
• Bomb can now Spam Dash if below Max Dash Speed.
• Fixed a few miscellaneous bugs.
• Mod is now limited to characters currently compatible, fixing a number of bugs relating to Modern Sonic and Adventure Sonic.

Forgot to apply the Fall Speed change to Bouncing.

Increased Fall Speed from FRACUNIT/2 to 3*FRACUNIT/4 in response to a review. Also fixed a few bugs related to being able to move during a Spin Dash / Spin Dash Equivalent.

Accidentally re-added an old bug in the original Momentum+, so one more hotfix I guess.

Something else broke while updating again. If this keeps happening, I'm going to blow a gasket...

Broke something else while updating and had to do it again. Also patched a few more bugs.

Fixed an issue where Sonic would immediately enter the Jump state in certain situations after leaving the ground.

• Reduced Tails' Max Flight Time from 8 seconds to 2 seconds to encourage bouncing on enemies to refresh it.
• Not holding a direction while Spinning now reduces speed faster than when holding a direction, in response to the controls feeling "slippery".
• Metal Sonic's DashMode now accelerates on the ground again in response to a review.
• Fang can no longer use Popgun after Bouncing or after already using Popgun, as originally intended.
• Squashed a few bugs.

Realized I messed up Bomb's Spin Jump and I forgot to rename the pk3 file, so I reuploaded the patch.

After my attempt to upload a custom build failed, I decided to use what I'd learned to recreate that build using LUA. There are too many changes to list here, but I'll be updating the main page shortly.
