Translation of the user interface

[nightflyer88]

A translation of the user interface would be very helpful. I have made a try, but somehow does not work: #nightflyer88@40bed28

Maybe you have an idea why that does not work?

After executing "lupdate", the error message "lupdate warning: no TS files specified" is displayed.

Pulled this in here:

I added a setting to attempt using the system location automatically, and simplified the lookup code a little bit. The translation features seem a little weird to me (location names seem to always be in English), but it seems to map specific locales like "en_US" to "en", or "de_CH" to "de". Let me know if these changes break anything for you.

Cool !

Before you make a new release, tell me, then I make the German translation a little better.

It's in the 2.3 release already: ;-)

I'm mostly done integrating a simplified support for the esp8266 bootloader now, which I plan to release as as 2.4.0 next week.
