[Suggestion] Show foreign currency when creating expense transaction

[etnperlong]

Hi,

Thanks for your work fixing issue #95. This fix has made it much easier for me to record cross-border money transfers when paying off credit cards.

As I continue to use Pico to keep track of my foreign currency card (in HKD) purchases locally (by GBP), I found that there is no option for me to record the price in foreign currency.

I'd like to describe my usage scenario because in Europe/UK, the rewards for using a credit card are relatively low (usually only around 0.75% ~1.5%), but if I use a Hong Kong/US credit card, I can get around 4 ~ 5% cashback. So I tend to use Hong Kong/US credit cards in the UK to get higher rewards.

However, there are some FTF (Foreign Transaction Fee) charges, which are around 1.95% when I use these cards. This purchase (including this charge) will be recorded in the currency (HKD/USD) of the credit card. Therefore, I would like to record both the local currency (GBP) and the foreign currency amount (HKD) when I record these purchases, and use it to calculate the actual rewards rate I get when I pay my bill every month.

Pico currently lacks such a feature, I can only record the foreign currency (HKD) at the time of purchase and use the original Firefly III's UI to complete the information.

Since I don't know how to develop with Vue (Actually, I only know React 😂), I hope you will consider my needs and add such a feature, I will be eternally grateful! Thanks!

I understand the scenario but I don't think it's something that a large number of users would use. Not rejecting it but it's something that I can look into later.

My main focus is to keep thing simple and streamlined. It would be extremly overwhelming for new users to be present with a huge list of inputs for something as simple as recording as expense.

One oproach would be to add the "foreign amount" to the sortable list of form fields (make it hidden by default) and give advanced users the option to enable it.

Thank you for your help! I think this would be a balanced solution. I tried to read the code and let me create a pull request if I have time.
