Description

Discontinued national currencies that have been replaced by euro were not included so the UI will not be bloated. If there is a requirement to include discontinued currencies, they can be added later.

In several instances, currency symbols were changed in accordance with World Bank editiorial style guide. Codes stayed the same throughout. E.g. previously Danish crown was kr. in TB. With the addition of Norwegian and Swedish currencies, which also use crowns, it was necessary to change Danish crown from kr. to dkr, while the code remains DKK.

Additional currencies that were required do not have ECB FX in the existing api: KWD, QAR, SAR.
QAR and SAR have fixed exchange rate referencing US Dollar, these can be calculated based on USD FX.
KWD has been moved to follow up task #1440.

Closes #1154
