MBS FileMaker Plugin, version 8.4pr6

- Updated DynaPDF to version 4.0.22.59.
- Changed ImageCapture.OpenDevice and ImageCapture.CloseDevice to only request closing of the current session, if there is one open to avoid freeze.
- Fixed crash with GMImage.SetIPTCProfile, GMImage.SetICCColorProfile and GMImage.SetProfile if called with empty parameter.
- Rewrote syntax highlighting partly for formulas. Should now be faster and not move the cursor position after deleting text.
- Fixed CNContactStore.ContainerForGroup function.
- Fixed problem with Activate/Deactivate showing up in layout dialog, where it shouldn't.
- Added AVRecorder.CurrentQRCode, AVRecorder.HasQRCode, AVRecorder.StartQRCodeDetection, AVRecorder.StopQRCodeDetection functions for live barcode detection on MacOS and iOS.
- Improved variable check for next FileMaker version.
- Disabled variable check in debugger to reduce crash on closing debugger or reading other script lines.
- Fixed crash with unrecognized selector and FMXRolloverPopupButton prompt.
- Fixed Copy & Paste for preferences dialog. Now it should work for pasting license keys.
