New object field - Step 2 - New field type: Currency

[Bonapara]

Desired behavior

The Unit pick list should enable people to choose between:

1. United States dollar (USD)
2. Euro (EUR)
3. Japanese yen (JPY)
4. British pound (GBP)
5. Canadian dollar (CAD)
6. Swiss franc (CHF)
7. Chinese yuan (CNY)
8. Hong Kong dollar (HKD)

Do not implement the uniqueness & required features yet.

If there are any existing records with this field, display the value of the first non-empty field. Otherwise, the preview value should be $2.000. (without space between the $ and the number behind)

We talked with @Bonapara and we realized that currency unit is at the field level. So design above for setting page is incorrect. And we will need a new design to change the unit at the field level

[FelixMalfait]

Actually we discussed it again and we can keep "unit" but as a defaultValue for the field
