Allow a name suffix in the bluetooth alias

[MartijnBraam]

Currently PineTime watches are detected by the device alias so if the user changes the alias they are no longer listed in Siglo. This is pretty hard to fix because there's no good way to actually detect it any other way. This fix lets people at least add an suffix to the alias to differentiate devices.

Fixes #54
