Major refactor and cleanup of EAS code

    * Rewrote push logic to encompass multiple folders (i.e. calendar/contacts)
    * Change inbox from push frequency to ping frequency after initial sync
    * Implement upsync logic for email (i.e. sending changes to the server)
    * Did cleanup of some files (there's still some to do) re: format, style
    * Initial one-way sync of Contacts data - add and delete are implemented
    * Created adapter package for all parts of the EAS adapter
    * Created utility package for utility code that will eventually be merged
      with code in the Email application (Base64, QuotedPrintable, etc.)
    * SyncManager/AbstractSyncService can be used in the future for other
      protocols, especially IMAP push
