[BUG] Cape loading lags the client

[SenkJu]

Describe the bug When you open up your inventory or switch to f5 mode for the first time the client loads the cape asggined to the current account. Everytime it does so, the client lags for ~1 second depending on the cape. This is especially annoying when playing on servers where you die and respawn a lot. Cape loading should either be running on a seperate thread or capes should be cached.
