* A modified version of the wxInfoBar class that allows us to:
* * Show the close button along with the other buttons
* * Remove all user-provided buttons at once
* * Allow automaticly hiding the infobar after a time period
* * Show/hide using events
* * Place it inside an AUI manager
*
* This inherits from the generic infobar because the native infobar
* on GTK doesn't include the icon on the left and it looks worse.
*
* There are 2 events associated with the infobar:
*
* KIEVT_SHOW_INFOBAR:
* An event that tells the infobar to show a message.
*
* The message text is contained inside the string component,
* and the message flag is contained inside the int component.
*
* Sample event creation code:
* wxCommandEvent* evt = new wxCommandEvent( KIEVT_SHOW_INFOBAR );
* evt->SetString( "A message to show" );
* evt->SetInt( wxICON_WARNING );
*
* KIEVT_DISMISS_INFOBAR:
* An event that tells the infobar to hide itself.
