Edit Form View for FileTagger

Whenever an MP3 song is selected, we want to be able to execute an action on it: edit tag. This choice should go in context menus for all playlist views, as well as in the MP3 pull-down menu.

Write a form view for FileTagger, called Mp3TagForm, that provides the user with editable, viewable information about all of the songs properties. We need action buttons as follows:

• Ok Perform a commit() on the FileTagger (which stores changes to the actual id3tag in your MP3 file) and return to main screen (hide form).
• Reload Discard changes and reload tag info.
• Cancel Discard changes and return to main screen (hide form).
• Play Play the track.

When editing a song, it should use a QLineEdit for each QString field and a QComboBox for the preference values. Keep in mind that the URL, filename, and track length are non-editable fields. Finally, you can use Designer or hand-code your dialog.
