Added the sort order type „Distance“ which is available if the current user has picked their current location from the Autocomplete List (since 1.0.0-b6).
Please note that the calculation of distances requires a formula that is computationally expensive. However, a few hundred calculations should not be a big problem, even for a low performance server. But if you have a very large user base, a member search with distance sorting on a global level may be „too much“ for your server. If that is the case let me know and I will add an option to restrict „distance sorting“ to non-global level searches.
