added warning message for Nuke bug when script tries to restore panel upon being lodaed
adding __str__ to identify panel to remote-load it via nuke.onScriptSave callback
fixed re-loading of tasks when nuke script is saved while widget is open
not too happy with solution thoug (re-creating taskContainer and scrollArea)
still need to re-enable main UI after this
main ui now enables itself when new settings file is loaded after widget was initialised withuot one
cleaned up print statements and avoided unnecessary calls to findAndReload when nuke script isa saved that already had been sdaved before
