In Melee the first 6 frames of a roll can be interrupted with an item throw. However, the item will always be thrown in the direction the roll is moving. This has been referred to as a "glide toss" and is rarely used. (I think this tech or something similar is in Brawl but I'm honestly not sure how it works there.) This code allows you to input either a forward or backward item throw during the roll interrupt window. Note that in Melee rolls can only be interrupted by item throws using the A or Z buttons, not the C-stick.
The first two item throws are enabled by this code. The second two (after I mess up and roll) are possible in unmodified Melee.
Also, the first 3 frames of an airdodge can be interrupted by an item throw (C-stick or A/Z button). When doing so, velocity is reset to what it was before the airdodge began. This second code replaces this behavior such that instead, momentum is partially conserved from the airdodge into the item throw. This is similar to the AGT tech seen in Project M (but in Melee airdodges don't catch items, so I hope you're good at Z-catching!)
