Provisionally changed link to Mobility on the Play Store to be edu.ucla.cens.mobility rather than the dummy one that was there before. Will change if we decide to change the name of the combined Mobility APK.
Renamed all references to edu.cens.ucla.mobility to org.ohmage.mobility, updated glue package name accordingly.
