Proxitok enable state reading from OSM value instead
In MainActivity.java
public static String SET_OSM_ENABLED = "set_osm_enabled";
public static String SET_PROXITOK_ENABLED = "set_osm_enabled";
SET_PROXITOK_ENABLED is being set to the same string as SET_OSM_ENABLED so when read from or written to app_prefs.xml, it will couple Proxitok and OSM's enabled state together instead.
