Briefly pause shop refreshing when you find an egg

[Sersemina]

We have this feature for the epic items - you get this "Wow" message to draw your attention to the epic item and the refresh button is disabled for a second. Today I defeated Dragopyr and decided to search for his egg in the weapon shop. I found it once, but I lost it half a second later, because I was clicking too fast and I couldn't react. Luckily I found it again soon after that, but I was a lot more careful this time.

For the record - I found the egg twice with 19 mushrooms so it is not that hard to find. I didn't notice, but I think the egg didn't cost anything (at least no mushrooms).

Thanks for your suggestion!
