settings: add option to force-reload the app

Add an option to force-reload the app.

Currently, Auxio will load music once and then never re-load it. This
is a really decision I made early on and now regret completely. The
only way to remedy this properly is to create an automatic rescanning
system, but that is a major technical undertaking that I want to save
for later.

Resolves #71.
