Have sequence analysis properly use filters from taps. 

Sequence analysis has its own "filtering" system that required its
tap functions to look for some "filter flags".  register_tap_listener()
already comes with a filter argument, so use that to simplify logic
of tap functions in dissectors.
Also have Qt GUI for Flow Graph look like other dialogs that have a
"Limit to display filter" checkbox.
