Hello Unreal Engine 4.21

Thanks to a user I've been talking with I went through this old code and fixed a few lingering bugs, While I've been very busy working on my project Super Powered Battle Friends. I felt this terrible guilt leaving old code lying around so hopefully this leads to more bug fixes and cleanup for current unreal versions. To begin here is an update to support 4.21

• Fixed Forward Specials, Forward Smashes, Dash Attacks, Dodge rolls not cancelling their own movement
• Adjusted Freezeframes so they aren't so long originally this was to help exaggerate them for users to notice them
