translations: initialize water type strings at run time

Browse source 
The water type strings were static and therefore passed through
gettextFromC::tr() before main(). One would hope to get a warning
in such a case, but this is not the case.

Therefore, use the QT_TRANSLATE_NOOP macro to register the strings
in Qt's translation system and translate the list when needed.
