Adding a dockable widget to the main window. Currently non-
functioning, but learning how the QDockWidget functions.
Added new image, moved cliprinter to lib/, working on getting
widgets to function
Got widgets working thanks to this site:

Fixed Icons, set icon path that won't change regardless of where
project is run from. Title bar set properly again, application
gets its icon (subject to change) and structure further modified.
