Added currencies and price changes

Recently Steam added new currencies, few things got in the way (my apologies) and it took me awhile to update them but we now support all the recently added currencies.

Those incude: Argentinian Peso (ARS) Costa Rican Colón (CRC) Israeli New Shekel (ILS) Kazakhstani Tenge (KZT) Kuwaiti Dinar (KWD) Polish Zloty (PLN) Qatari Rial (QAR) Ukrainian Hryvnia (UAH) Uruguayan Peso (UYU) Vietnamese Dong (VND)

We've updated the prices for all the other regions as well, and lowed the price of the game from $9.99 USD to $4.99 USD.

Thanks for playing, and for those who have yet to play we hope you enjoy it!
