Option to sort by recently usage

[golopot]

When this option is enabled, the entries will be sorted by time of last usage.

That could probably solve an annoyance that makes the authenticator randomly closing and only exhibiting one entry.... but I still rather have the option to sort and leave it as I sorted: it's counterintuitive to keep doing auto-sort as your brain will remember where it was, not where it will sorted to.
So... if this comes as feature, please allow me to disable it. Thanks.
