confirmation button on plat purchases.

[Catwomann]

I just accidentally tapped on xp elixir, and wasted 4 platinum on it and I am already capped and don't even need that elixir.

We surely need a confirmation box for all platinum purchases.

This was an accidental tap, what if some water spills on a touchscreen device (as most ppl play the game on android and iOS devices), it can go haywire. Someone's total plat can end up being drained on elixirs.

Pls add confirmation box.
