What would be the best approach to translate an app?

As I'm sure you noticed, we currently do translation like this: https://github.com/espruino/BangleApps/blob/master/apps/locale/locale.html#L74

translate: s => {s=""+s;return locale.trans[s]||locale.trans[s.toLowerCase()]||s;},

The way it's handled, that translation array gets loaded into RAM as soon as locale is used.

However, it could easily be modified to:

translate: s => {
var trans = { ... actual translation data here ... }
s=""+s;return trans[s]||trans[s.toLowerCase()]||s;},

Since function code is kept in Flash, this would be nice and tidy and would allow translation without a massive memory usage hit.

And I think maybe we could do something smarter with the translation, like:

• Handle capital letters (No/no) specially (could be done with regex)
  
• Match on part of the string (so just New Alarm from > New Alarm could get picked up)
