Add weapon swap while dashing

[thin ginkgo]

Currently when you dash on the ground you can't swap weapons, and any input during a dash doesn't have effect after the dash animation is done.
On kbm it's not as bad because you can spam your gun selection key without worry but on controller their is no designated key for each slot so spamming swap can cause you to just swap back to the empty gun anyway.
Would be nice to be able to swap while dashing or at least let the input register so when the animation finishes your character will swap weapons after.
It's difficult to time it exactly with the end of the animation and causes a lot of confusion when you think you swapped weapons just to pull the trigger and realize you didn't and gg.

Also add weapon swap to the landing roll animation, or at least a register so it swaps after without consecutive inputs.

Just learned that if you dash after you jump and swap weapons it will register the input and swap weapons after animation but if you dash while grounded it won't...hmm.
