0.5.0: riordino come l'app ufficiale (home, Dati, Impianto)

- home: temperatura esterna e in casa/assente in alto, messaggio di stato,
  scheda impianto con temperatura stanza e acqua calda; comandi sotto
- pagina Dati: calore prodotto, elettricita' usata, COP acqua calda e
  riscaldamento, risparmio, CO2 evitata, Smart Tariff Control (mese per mese)
- pagina Impianto: stato, termostato a parete, versioni software, errori
- bridge 0.4.0: rotta /stats (servizio statistiche del cloud) e blocco
  dispositivo in /summary (ID breve, versioni, termostato)
- C++: parseStats, formatNumber, formatMoney, monthLabel (separatore e
  valuta secondo la lingua); 61/61 verifiche del nucleo
- anteprime aggiornate (dati, impianto) in inglese e italiano
