This reverts commit 5d24254a.

Some countries do not exist any more, some currencies do not exist. Some countries (and currencies) started to exist recently. Some currency codes are changed (mistype or result of denomination).

Also I tried to keep the moodle formation of the name of the currencies. The first word is not the country name but the 'belonging-to-country', i.e. not 'Sweden Krona' but 'Swedish Krona'. For some countries it was not so easy to find the correct spelling.

And finally there were some mistakes in the list, like 'Schilling' instead of 'Shilling', 'Riyal' instead of 'Rial', etc. I used currencies spelling from ISO.
