Add previous game state to context.using_consumeable

[Maelmc]

When using a consumable, G.STATE becomes G.STATES.PLAY_TAROT, which makes it not simple to check the actual game state while using a consumable, for example when in the shop or in a pack. Having the previous game state included in the context would help for this kind of situation.

When using a consumable, G.TAROT_INTERRUPT stores previous G.STATE and G.STATE becomes G.STATES.PLAY_TAROT. After that, G.TAROT_INTERRUPT returns its value back to G.STATE before becoming nil. That should be more than enough to pull the check.

Oh I wasn't aware of that, pretty useful thank you
