Title: Merge FlxPTColor into FlxColor and move FlxVelocity

Integrated `FlxVelocity` into the util package and moved some functions it cotained that are more fitting in other util classes:

- org.flixel.plugin.photonstorm.FlxVelocity -> org.flixel.util.FlxVelocity
- `FlxVelocity.distanceBetween()` -> `FlxMath.distanceBetween()`
- `FlxVelocity.distanceToPoint()` -> `FlxMath.distanceToPoint()`
- `FlxVelocity.distanceToMouse()` -> `FlxMath.distanceToMouse()`
- `FlxVelocity.distanceToTouch()` -> `FlxMath.distanceToTouch()`
- `FlxVelocity.angleBetween()` -> `FlxAngle.angleBetween()`
- `FlxVelocity.angleBetweenPoint()` -> `FlxAngle.angleBetweenPoint()`
- `FlxVelocity.angleBetweenMouse()` -> `FlxAngle.angleBetweenMouse()`
- `FlxVelocity.angleBetweenTouch()` -> `FlxAngle.angleBetweenTouch()`

Also completely merged `FlxPTColor` into `FlxColor` now.
