[Bangle.js] Add buzz on back widget pressed

[RKBoss6]

This is in regards to Issue 2641
This adds a buzz to confirm that the back widget was selected.

Great - and just to check, this is tested (via the tutorial mentioned in #2641) and it works ok for you?

@gfwilliams Hi! I just tested this a few times, and it works for almost everything. The place where it doesn't buzz, however, is right after you open an app like settings, and press the back widget. It simply loads the clock, and does not buzz. Do you know why this might be? Thanks!

Do you know why this might be? Thanks!

Ahh, yes - it'll be because it immediately resets the device to load the new app, so the vibration motor is turned off basically as soon as it's turned on. For it to work nicely b would have to return the promise, then you could do b.then(() => options.back())

@gfwilliams That works now, I did not update the Bangle_setUI_Q3.min.js file, should I do that?
Additionally, what is the difference between the Bangle_setUI_Q3.js and Bangle_setUI_F18.js files?

[gfwilliams]

Thanks - right now you've got Bangle.setUI= in there, and you could just return the Bangle.buzz(30) promise I think (the try was to work around an emulator issue that's fixed. So I've just added this myself and minified the file.

what is the difference between the Bangle_setUI_Q3.js and Bangle_setUI_F18.js files?

F18 is for Bangle.js 1 (it's the codename of the original watch that was used)

@gfwilliams Ok, thanks so much for the help!

@gfwilliams Until the next version of firmware is released, I was thinking of making an app for this functionality, wdyt?

[gfwilliams]

Well, you can just install a cutting edge build and get it, so personally I don't think an app would be that much help?
