Add a Busy status to SyntaxLineEdit.

For CaptureFilterEdit it's possible to have an indeterminate state while
we're waiting on name resolution. Add a Busy status to SyntaxLineEdit
and set the text color to a mix of the normal foreground and background
colors (gray on most platforms).

Make the Busy state valid so that we don't have to wait on an
annoyingly-long name resolution to start capturing.

Update the global capture option filters using the main welcome capture
filter when we start a capture instead of when we've finished checking
the filter syntax.

Connect the CaptureFilterEdit returnPressed signal no matter what so
that we can start a capture by pressing return in the welcome screen
CaptureFilterEdit.

Add a fake resolution timeout to the CaptureFilterSyntaxWorker debug
code to make testing the different states easier.
