Support WooCommerce Multicurrency

Hello Emre,

To support multi-currency caching for https://woo.com/products/multi-currency/, $this->cacheFilePath needs to be set depending on the active currency (something similar to what you do for gtranslate in cache.php).

I have the code ready. If you’d like to add it to the free version, I’ll post it here. If you rather have it in the paid version, please contact me at [email protected]

Let me know.
Thank you!
