RFC: Add ISO Currency Code support to KLocale

[John Layt]

Hi,

I am proposing to change KLocale to support the ISO 4217 Currency Code 
standard (http://en.wikipedia.org/wiki/ISO_4217).

The existing currency support is based on a free-text currency symbol field. 
This leaves applications such as KSpread, KMyMoney, Skrooge, Kraft, 
KEuroCalc, and various Plasma widgets to provide their own implementation of 
the ISO codes and translations of the names, leading to unnecessary 
duplication and inconsistency.

This is an initial proposal aimed at improving the l10n and i18n issues, so 
comment is particularly sought from the translation teams on a number of 
issues, especially given how much work may be involved for them.  

I am also seeking comment from the various financial applications to ensure 
the initial implementation is flexible enough to meet their needs both now and 
in the future.

Details of the Design and Outstanding Issues are at 
http://techbase.kde.org/Projects/kdelibs/localisation#ISO_4217_Currency_Code_Support 
and the initial code can be found on the Review Board at 
http://reviewboard.kde.org/r/2049 .

Thanks!

John.
