Modified upload process to remove Google Drive Upload Confirmation box. Added code to upload all files to a directory on Google Drive root. As part of the move to single uploads the main UI was changed. A radio button was added to each item on the List Adapter. Now a user can only select a single app to upload at a time. upon successful upload the corresponding checkbox for that app is checked. Removed passing zip files via intents, instead just the directory reference is passed, as before, and the zip file is taken from that.
