Add initial capture filter support.

Add CaptureFilterCombo and CaptureFilterEdit classes, similar to their
display filter counterparts. Add a CaptureFilterSyntaxWorker class which
runs a syntax check in a background thread similar to the threaded code
in capture_dlg.c. Add a bunch of related signal and slot plumbing. Other
minor fixups.
