Refactor Busy out of CatchingPage

[jakubsuchybio]

Change details

• Remove Busy from CatchingPage
• Remove server-side InventoryUpdate and replace it with local descreasing of thrown items
• Disabled wrong state after catching
• Removed 5s wait when missed

Other informations

• Wrong state was, when you catch pokemon, then the pokeballButton got enabled and you could click it and break the game or maybe get yourself banned because it would send another catch request for already catched pokemon...

I'm not really sure about this. We need to update the inventory even if the Pokemon escaped or we're not showing the correct Pokeball amount. Doing lastused.Count-- is not enough because the user may switch to another ball and then switch back, seeing the wrong value.
