store last five most recently used currencies in the currency toolbar drop-down

Refactory
Cause
Currency must be added in the MRU list in  SvxCurrencyToolBoxControl::execute
method.
Unfortunately in this point the only information available is the number format.
It is not possibile to infer currency from number format  (e.g: both  USD and
AUD use symbol $).
Encapsulating currency data
In order to solve the problem currency data is enacpsulated in a SvxCurrencyData
struct. Added a vector of SvxCurrencyData to SvxCurrencyToolBoxControl.
Static and non static call
Former static SvxCurrencyToolBoxControl::GetCurrencySymbols has been
preserved, as it is called by SvxNumberFormatShell.
A new GetCurrencySymbols is used by the control.
To avoid code duplication, both functions call a static private function
inner_GetCurrencySymbols.
MRU Currencies
MRU currencies are stored in another member vector m_mru_curencies:
During currencies vector population (inner_GetCurrencySymbols) a space is reserved
on top of vector for mru currencies.
A new method addMruCurrency updates m_currencies. This method is called in
SvxCurrencyToolBoxControl::execute
