Separate creating wxUILocaleImpl from using it

Browse Source 
Add Use() virtual function which can be used if the newly created
wxUILocaleImpl object should be used as the default UI locale.

Currently Use() is always called after creating a new wxUILocaleImpl, so
adding a separate function just seems to complicate matters needlessly,
but this won't be the case any more soon, when wxUILocaleImpl could be
created for using them for other purposes than making them the default.

No real changes yet.
