JOptionPane for Errors, general refactoring, deprecated class removed (CameraRenderer) moved into Swing now

modified:
/ SwingCCTVManager ; Error Pane, refactoring
/ WebcamCaptureLoop ; cleanup method for closing cameras reliably, and some MessageDialogs for error handling (just fails lol)
/ SwingCameraWindow ; refactor some legacy code into a "modern" lambda function , Message Dialog for error handling , and some g2d stuff (paintComponent)

removed:
- CameraRenderer.java ; Deprecated Component, was used for SWT GL Surfaces. We dont do that now!
