Investing now refreshes shop page

[Pri]

An issue with investing on the shop since I added it is if you have a Free investment card you may see "FREE" appears on all the slots, but once you've used it on a single item the FREE stays on the rest of the items on the shop even though it will cost you money to use them.

I've now corrected this, if you have any FREE investments active when you visit the shop page it will refresh after you perform an investment. If you don't the page won't refresh. This will completely fix the problem and I'm very sorry that many of you wasted money investing in items you didn't intend to.
