Don't prompt user to install, if apk is in cache from a previous install

Browse Source 
Use SharedPreferences to keep track of whether we are in the middle of
an install for a particular apk or not. If sothen the presence of an
.apk file in the cache means we need to tell the user (in the updates
tab) that a file is ready to install.
