Allow reloading app list in sunmenu
Adds an option to settings to reload app list, and exposes a function to do so in pyst3m/utils as reload_app_list
.
This also implements it in:
- app store/gr33nhouse: Automatically reloads app list after installing an app
- fil3s: Automatically reloads app list after deleting an app
might be useful also in the future if we ever implement exiting from usbms mode without a restart.
