Correct bug where adding a new tag via the tag tree automatically assigned it to the current note.
Change API key to new one per Evernote's request.
- Added basic error message displays to the communicationmanager class.
- Checked that tag parent guid is not "".  If it is an empty string then Evernote
complains about it when syncing.
Add basic support to upload notes owned by the user.  Notes in linked notebooks are not uploaded.
Remove debugging line.
