[ENHANCEMENT] Other currency options

[niklaszantner]

It would be nice to have the possibility to set other currencies, like euro instead of dollar

I found some types from kraken like this XETHZEUR here:
https://github.com/Beldur/kraken-go-api-client/blob/master/types.go

And you'll definitely get a beer-wise donation for that!

I already tried to simply replace

@SerializedName("XETHZUSD")
private KrakenPriceApi mPriceApi;

with

@SerializedName("XETHZEUR")
private KrakenPriceApi mPriceApi;

But somehow my Android Studio screws up with building (outdated maven I guess).

Thank anyway for having a look at this.

Sorry did not have the time to change anything for a while now!
I'm gonna try to include that when I'll have the time (probably around September, I know that's far sorry :().

Cheers,
