Reuse the same XRC function for all translations

Translate all strings in the new GetNodeText() function replacing the
old GetText() which was mostly used for translatable strings before --
except that <item> tag contents didn't use it because it also performed
string unescaping, not wanted for the control items, in addition to
translation.

Replace the old GetText() (while still keeping it for compatibility,
i.e. to avoid breaking any custom XRC handlers using it) with the new
function which is more flexible and can be used for all tags.

No real changes, this is just a refactoring.
