v1.1 (Unofficial 1.4.4 Port)

Cyrillya's "Whip and Spear Fix" mod ported to 1.4.4 (spear part not included).
Replaces the IL Edit (which relied on code that was removed in 1.4.4) with a simple Detour of the whip AI.

The details: Unlike vanilla, The player's itemAnimation never reaches 0 while swinging with auto swing with whips in tModLoader. Thus, it doesn't let you swap to another item until you've let go of the attack button. This mod just sets the player's itemAnimation to 0 if it is 1, which allows you to swap to other items.
