TwoWire::begin has reversed parameter order than on ESP8266/Arduino

[luelista]

I just spent a few hours debugging a small program I ported from ESP8266/Arduino to Sming. The problem was that I called Wire.begin(scl, sda); as it works on the Arduino implementation. On Sming, the order of params is reversed: Wire.begin(sda, scl);

I'm not sure if this should be changed here or there, but I'd at least like to put this here as a warning for other people searching for problems with I2C on Sming.

I remember we discussed this before. @avr39-ripe @slaff any opinion on this?

I think we should make Wire.begin the same as ESP8266/Arduino. Update Wire implementation and update examples app.

@avr39-ripe Agreed. Can you create a new PR?

Should be fixed with PR #1193 which is merged now in the develop branch.
