major restructuring, moving dialog, message, menu, option menu, task, type IDs into Id in a similar structure as the generated R, also introducing a BaseActivity class that almost all activities derive from, which generates some common dialogs, handles the progress update, thread management, and thread communication
also adding first draft of encrypt file activity, not very functional yet
