MEDIUM / CORE-49 Some localized were not computed. Indeed FIB Localized
were not parsed (ie: <entry key=.. lang=..>value</entry> has to be
replaced by <entry key=... lang=... value=... /> and pamela tags have
been refactored accordingly).
Also add the main localized as parent for FIBLocalize, so if an entry is
not found in the FIB the entry is seek in the parent.
