Changes to Gateway QT frontend to allow status screen to display AET, hotname, DICOM port, and connection details
- Refactors to application structure to allow multiple resolutions
- Refactored main window to only inherit from QMainWindow
- Init of mainwindow widget now performed from UI file, allowing the widget/layouts to be edited from QT designer rather than requiring it be modified in code.
- Moved logo layout to a dynamic grid with spacers to allow for the UI to be used on multiple size display devicees.
- Started moving UI files to "resources" folder.
- Added labels to display AET, hostname, and port
